康厚超 440c001a20 feat(band): add Band.us adapter — bands, posts, mentions, post commands (#532)
* feat(band): add bands, posts, and mentions commands for band.us

- bands: lists all Bands via get_band_list_with_filter intercept
- posts: lists posts from a Band via get_posts_and_announcements intercept
- mentions: shows @mention notifications via get_news intercept

All use Strategy.INTERCEPT since band.us API requires an HMAC md header
generated by its own JS. SPA navigation to /band/{no}/post triggers the
band list and posts APIs; bell + @メンション tab click triggers mentions.

* refactor(band): clean up all three band adapters

- Fix doc comments: Band uses XHR not fetch; clarify INTERCEPT rationale
- bands: replace for-loop with flatMap; explain why band page nav is needed
- posts: remove item.post ?? item fallback (API always wraps in post); rename
  finalRequests → requests for consistency; extract stripBandTags helper
- mentions: remove redundant ?? defaults (args have defaults defined); fix
  unreadOnly bug (was not applied to post/comment modes); consolidate Band tag
  stripping to single regex; cast kwargs types directly instead of converting;
  add comments explaining last-response strategy and 'referred' filter flag

* fix(band/posts): handle mixed post/announcement items from API

get_posts_and_announcements returns both regular posts and announcements
that have different shapes — some lack post_no and wrap differently.
Restore item.post ?? item fallback and filter out items with no resolvable
identifier to prevent undefined in URLs and empty rows in output.

* feat(band): add post command — full post export with comments and photo download

Exports the complete content of a single Band post:
- Post body (with Band markup tags stripped)
- All comments in chronological order
- Photo URLs shown inline, or downloaded with --output <dir>

Uses Strategy.INTERCEPT with a broad 'band.us' pattern to capture both the
batch request (embedding get_post) and get_comments in one SPA navigation.
Responses are identified client-side by shape: batch_result array vs items
array with comment_id fields.

* refactor(band): replace XHR interception with direct DOM extraction

- bands, posts, post: navigate directly to target URL instead of home→SPA detour
- All three switch from Strategy.INTERCEPT to Strategy.COOKIE with navigateBefore: false
  (bands uses framework pre-nav to home; posts/post disable it and goto target directly)
- DOM extraction polls for specific content elements rather than fixed waits
- post: confirm selectors via browser inspection (a.text, time.time, .sCommentList,
  .sReplyList for nested replies); add --comments flag to skip comment fetch
- posts: extract from rendered post list DOM; correct comment item selector (div.cComment)
- Fix: post empty-result guard changed from && to handle null data safely
- Fix: photo download now checks HTTP status code before piping to avoid writing
  redirect HTML into image files
- Fix: mentions unread client-side filter skipped for 'mentioned' mode since
  server already filtered via 未確認のみ button click

* fix(band): address code review feedback

- post: replace manual http/https download with shared downloadMedia utility
  (handles redirects, timeouts, stream errors correctly)
- post: fix photo URL resolution to use location.href as base, handling
  protocol-relative and relative URLs without throwing
- post: switch to node:-prefixed imports per repo convention
- post/posts: remove redundant ArgumentError guards — framework already
  validates required args before func() is called
- mentions: INTERCEPT strategy is intentional (Band HMAC prevents DOM-only
  approach for notifications; update PR description to clarify)

* fix(band): address second round of code review feedback

- bands: tighten href selector to /band/{id}(?:/post)?$ so feed/post-detail
  links are excluded; only sidebar navigation links match
- mentions: replace fixed page.wait(2) sleeps with polling on
  getInterceptedRequests() — waits up to 8 s per action, exits as soon
  as the expected number of captures arrives (avoids flakiness on slow XHR)

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(band): fix selector bugs found during testing

- bands: use a.bandCover._link + p.uriText + span.member em selectors
  (previous a[href*="/band/"] + .bandName combo leaked "メンバー" text)
- posts: use article.cContentsCard._postMainWrap + span.count selectors
  (previous li._postListItem selector matched nothing; DOM changed)
- mentions: fix page.wait(500) → page.wait(0.5) (was waiting 500s not ms);
  use timestamp-suffixed URL to force fresh page load each run so the
  notification panel is closed; fix get_news vs get_news_count capture
  ambiguity with result_data.news check; replace cumulative waitForCaptures
  with waitForOneCapture (getInterceptedRequests clears array on each call)

* fix(band/mentions): use CSS class selector for bell button instead of locale-dependent text match

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(band): address third round of code review feedback

- post: pass browser cookies to downloadMedia so Band's login-protected
  photo URLs don't fail with 401/403
- post: include photos.length in empty-result guard so photo-only posts
  are not falsely reported as not found
- mentions: accumulate captures across poll iterations so get_news_count
  responses don't cause early exit before the real get_news arrives
- mentions: update docstring to match actual implementation (client-side
  filtering, no tab-click)

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(band): address fourth round of code review feedback

- mentions: fail fast with a clear error when bell button is not found,
  instead of silently no-op and waiting 8s before EmptyResultError
- post: use shared formatCookieHeader() instead of manual cookie string
  construction

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(band): address fifth round of code review feedback

- mentions: replace fixed page.wait(2) with polling for bell button
  readiness (up to 10s), eliminating the fixed sleep and fail-fast
  when the selector is missing
- mentions: add explicit !newsReq guard with a clear error message when
  get_news capture times out, instead of falling through to a misleading
  "No notifications found"
- posts: skip posts with no permalink href instead of emitting a bogus
  'https://www.band.us' URL

* fix(band): address sixth round of code review feedback

- post: only send Band cookies to *.band.us photo URLs; third-party CDN
  URLs are downloaded without cookies to avoid cross-domain cookie leakage
- bands: strip non-digit chars before parseInt so member counts like
  "1,234" parse correctly
- posts: same fix for comment counts

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(band): address seventh round of code review feedback

- posts: check limit before push so --limit 0 returns empty result
- post: indent replies proportionally by depth ('  '.repeat(depth))
  so multi-level threads remain readable in table output

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(band/bands): anchor href regex to prevent matching post-detail URLs

Pattern now requires /band/{id} or /band/{id}/post (with optional trailing
slash) so deeper paths like /band/{id}/post/{postNo} are excluded.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(band): address ninth round of code review feedback

- mentions: guard bell click with a boolean return so a disappearing
  element throws a clear EmptyResultError instead of a raw TypeError
- post: wait for comment list container instead of first .cComment so
  posts with zero comments don't incur a fixed 6s delay

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(band): use page.getCookies() for login detection across all commands

Replaces document.cookie.includes('band_session') with
page.getCookies({ domain: 'band.us' }) so login detection works even
if Band.us marks the session cookie as HttpOnly in the future.

* fix(band): address eleventh round of code review feedback

- mentions: replace EmptyResultError with SelectorError for missing/
  disappeared bell button — produces a clearer SELECTOR error code
- post: assign per-photo filenames using a global index across both
  download batches so band-hosted and CDN photos don't overwrite each other

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(band): address twelfth round of code review feedback

- post: derive file extension from URL path and include in filename
  (e.g. photo_1.jpg) so downloaded photos have correct extensions
- posts: remove dead code guard (!url && !content) — url is always
  non-empty here since href-empty posts are already skipped above

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(band/post): use url-scoped getCookies for photo download auth

Domain-scoped getCookies may omit host-only cookies scoped to www.band.us;
using url: 'https://www.band.us' ensures all relevant cookies are included
in the auth header for Band-hosted photo downloads.

* docs(band): add adapter documentation and sidebar entry

Required by CI doc-check --strict: every adapter in src/clis/ must have
a corresponding docs/adapters/browser/*.md file.

* test(e2e): wire band auth coverage into default matrix
