Read the server-provided sender_name for both user and bot senders (previously
only users resolved) so message-read commands display bot names instead of raw
ids. The CLI opts into server-side name filling by sending with_sender_name=true
on chat-messages-list, threads-messages-list, messages-mget and messages-search,
as well as on the inline fetches that render nested senders: merge_forward
sub-messages and auto-expanded thread replies. Without it those nested-only
senders carry no sender_name and, with no fallback, render as raw ids.
Names come solely from the server (single source of truth): there is no contact
or mention fallback, so the contact scope is dropped from these four commands and
the contact/mention resolution code is removed. A sender the server does not name
falls back to its id; system messages show no name. The resolved name is exposed
in the existing `name` field (backward compatible); the duplicate raw
`sender_name` is stripped while the full `sender_i18n_names` map and `open_bot_id`
are preserved for consumers. No new permission scope is required. Updates the
lark-im skill docs.
Block 1 — field completion: audio renders <audio key="..." duration="Xs"/>
(falls back to [Voice: Xs]/[Voice]); post renders emotion -> :emoji_type:,
applies text.style (bold/italic/underline/lineThrough), passes through md;
sticker unchanged.
Block 2 — opt-in --download-resources (default off) on +chat-messages-list,
+messages-mget, +threads-messages-list: extract downloadable resource refs
during formatting (image/file/audio/video/media + post-embedded; sticker
excluded; merge_forward sub-items carry the top-level container message_id,
since the resources endpoint rejects sub-item ids with "234003 File not in
msg" and can only fetch a forwarded resource through the container; thread
replies get their own block), then download each distinct (message_id,
file_key) once into ./lark-im-resources/ with bounded concurrency (3), filling
back local_path/size_bytes; single-resource failures are isolated (error:true +
stderr warning). Path safety reuses normalizeDownloadOutputPath +
ResolveSavePath.
Batch download keys each file on disk by its unique file_key basename and only
appends an extension (from the Content-Disposition filename or MIME type) —
it does NOT substitute the server's Content-Disposition filename. Otherwise two
resources whose servers return the same filename (e.g. download.bin) would
resolve to the same ./lark-im-resources/ path and clobber each other
concurrently. The friendly "adopt the server filename" behavior is kept only
for an explicit +messages-resources-download with no --output.
Resource ref extraction guards against self-referential / cyclic merge_forward
prefetch maps (a real API sub-item list can include the container's own id or a
back-pointing merge_forward) via a visited set, so extraction terminates instead
of overflowing the stack. The container message_id is threaded through nested
merge_forwards as the download owner.
Also: document the feature (including the im:message:readonly scope requirement)
in skills/lark-im — SKILL.md is generated from skill-template/domains/im.md
(edit the source), plus the hand-written message-enrichment + 3 command
references.

Follow-up to #1095. The reactions auto-enrichment shipped, but on busy chats the strictly-serial per-resource fetches in EnrichReactions, ExpandThreadReplies, and merge_forward expansion stretched the command's wall time above 14s — enough that wrapper agents (30–60s wall-clock budgets) saw timeouts even though the CLI itself never errored. This PR parallelizes all three with the same bounded-concurrency pattern, batches the follow-up contact-API sender resolution so it doesn't fan back out into a serial stall, and fixes two correctness bugs that surfaced during review. Scoped to convert_lib/{reactions,thread,merge,content_convert}.go + tests + the 4 shortcut Execute hooks + the reference doc.
