Benjamin Liu 40592ea5fd fix(adapters): drop silent-sentinel row fallbacks across Apple Podcasts, Reddit, and Gitee (#1634)
* fix(adapters): drop silent-sentinel row fallbacks across Apple Podcasts, Reddit, and Gitee

Continues the audit-baseline cleanup from #1611 (lesswrong) and #1631
(wikipedia / 36kr / xiaoyuzhou / zhihu), and follows the direction set
by 71646158 (silent-empty-fallback resolutions across Douyin / Jike /
WeRead) and ee54eb8e (ignore sentinels in thrown errors).

Replaces silent-sentinel row fallbacks with the empty-string signal so
agents can tell apart "field has value Unknown" from "upstream returned
no value":

- apple-podcasts/search: episodes, genre
- reddit/saved: title
- reddit/upvoted: title
- gitee/search: language, description

All four files audited for downstream sentinel checks via
`grep -nE "=== ?['\"](Unknown|unknown|-)['\"]"`. None reference the
swapped values in control flow (verified against the v2ex/me.js class
of regression caught in #1631).

Intentionally skipped in this batch (will not flip to empty):
- gitee/trending.js:272: downstream `project.description !== '-'`
  check drives the mergedDescription fallback. Same control-flow
  sentinel pattern as v2ex/me.js. Stays on baseline.
- web/read.js x4: `'-'` lives inside rendered diagnostic lines
  (`lines.push(...)`), not row fields. Empty would render
  `  GET    /a/b` with a doubled space. UX placeholder.
- yollomi/{edit,video}.js x6: `file: '-'`, `size: '-'`, `credits: '-'`
  are user-facing status rows displayed to humans. Empty would
  collapse columns visually.
- zsxq/dynamics.js: `title: '[${d.action || 'unknown'}]'` is a
  template-literal-rendered title prefix. Empty would render `[]`.

Verified live: `opencli apple-podcasts search "lex fridman" --limit 2`
returns populated episodes/genre. `opencli gitee search "vue" --limit 2`
returns populated language/description. Baseline shrinks accordingly.

* test(adapters): add empty-signal coverage for the cluster-3 sentinel swap

Mirrors the cluster-2 test additions, pairing the sentinel value swap
in this PR with focused unit tests that mock the upstream to return
null / missing fields and assert the row surfaces an empty-string
signal instead of the old fabricated '-' / 'unknown' sentinel.

Coverage:

- clis/apple-podcasts/commands.test.js (+1 case): stubs the iTunes
  Search response with a result that has collectionId / collectionName
  / artistName populated but no trackCount and no primaryGenreName.
  Asserts episodes and genre render as '' (was '-' before this PR).

- clis/gitee/search.test.js (new): mocks Gitee's `so.gitee.com/v1/search`
  fetch with two cases - a hit that has only title + url (no langs,
  no description), and a hit that has all fields populated. Asserts
  the missing fields render as '' (was '-' before) and that populated
  fields pass through verbatim.

The reddit/saved and reddit/upvoted changes in this PR live inside a
page.evaluate template literal that fetches from reddit.com inside
the browser context, so the empty-signal branch is executed inside
the page rather than in adapter JS. They are 1-char `|| '-'` ->
`|| ''` swaps with no downstream sentinel consumer and the same JS
semantics demonstrated by the gitee + apple-podcasts tests above.

* chore: rebuild cli-manifest.json to drop stale entries from rebase

The previous rebase left a stale linkedin/people-search entry in
cli-manifest.json that was carried over from a sibling feature branch.
This branch does not include the people-search source file, so the
entry was an orphan; CI's build-manifest safety check correctly
refused to overwrite it. Regenerating with --allow-removals to drop
the orphaned entry, after which a normal `npm run build` is a no-op.
