fix(im): make reactions scope conditional so --no-reactions passes pre-flight (fixes #2352)

[Xuxchloris]

Fixes #2352

Problem

lark-cli im +chat-messages-list --no-reactions (and the sibling +messages-mget, +threads-messages-list, +messages-search) still fails its scope pre-flight with missing required scope(s): im:message.reactions:read even though reactions enrichment is explicitly disabled.

The shortcuts declared im:message.reactions:read in the unconditional UserScopes/BotScopes (or Scopes), so the framework's pre-flight required it on every invocation regardless of --no-reactions.

Changes

• shortcuts/im/convert_lib/reactions.go: EnrichReactions now enforces the reactions scope lazily via runtime.EnsureScopes(...) — the narrowest cohesive boundary shared by all four message-listing shortcuts — and fails soft on a missing scope (stderr warning + reactions_error: true on every message node including nested thread replies), matching the other enrichment failure modes. Never aborts main message output.
• shortcuts/im/im_chat_messages_list.go, im_messages_mget.go, im_threads_messages_list.go, im_messages_search.go: the reactions scope moved from UserScopes/BotScopes/Scopes into ConditionalUserScopes/ConditionalBotScopes (or ConditionalScopes), so the unconditional pre-flight no longer requires it — while DeclaredScopesForIdentity still surfaces it for metadata/diagnostics and --no-reactions callers never hit EnsureScopes.
• Tests: TestReactionsScopeIsConditional (scope is conditional for all four shortcuts, both identities), TestEnrichReactions_MissingScopeMarksAllNodes (missing scope → no API call, all nodes flagged, command output preserved); the convert-lib test token now grants the reactions scope by default (representative configured bot), with a scoped variant helper.

Verification

• go vet ./shortcuts/im/... ./shortcuts/common/... — clean.
• go test ./shortcuts/im/... — all pass except TestDownloadResourcePathSafety, a pre-existing Windows-only path-separator assertion (filepath.Join backslashes vs expected forward slashes) in an untouched file; CI runs on Linux.
• gofmt clean on all touched files.

Summary by CodeRabbit

• Improvements
  • Reaction data is now optional for message, search, and thread shortcuts.
  • Messages continue loading when reaction access is unavailable, with affected messages and nested replies marked accordingly.
• Bug Fixes
  • Prevented unnecessary reaction API requests when the required permission is missing.
  • Improved handling of recursively nested thread replies.
• Tests
  • Added coverage for missing permissions, skipped API requests, and nested reply handling.

📝 Walkthrough

Walkthrough

Reaction-read access is conditional for message shortcuts. EnrichReactions checks the scope at runtime, skips the API call when unavailable, and marks messages and nested replies with reactions_error.

Changes

Reaction scope handling

Layer / File(s)	Summary
Conditional reaction scope declarations shortcuts/im/im_chat_messages_list.go, shortcuts/im/im_messages_mget.go, shortcuts/im/im_messages_search.go, shortcuts/im/im_threads_messages_list.go, shortcuts/im/im_reactions_scope_test.go	The four message shortcuts declare reaction-read access as conditional for user and bot identities. Tests verify the unconditional and declared scope lists.
Lazy enrichment scope guard and regression coverage shortcuts/im/convert_lib/reactions.go, shortcuts/im/convert_lib/reactions_test.go	EnrichReactions checks the reaction-read scope before enrichment. When unavailable, it skips batch_query and recursively sets reactions_error on messages and nested replies.
Scope-aware runtime test setup shortcuts/im/convert_lib/runtime_test.go	Test runtime helpers accept configured token scopes and pass them to the credential provider and resolved token results.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to b84ab

The change makes the reactions permission conditional and preserves message output when reactions are disabled or unavailable; no actionable merge-blocking risk remains beyond normal checks and review.

- Around line 141-149: Update the []interface{} branch in markAllReactionNodes
to collect map-backed replies and recursively pass them to markAllReactionNodes,
rather than marking only the direct maps. Add a nearby regression test covering
an interface-backed reply with a nested child and assert reactions_error is set
on both levels.
