* feat(ci): add per-component labels for channels, providers, and tools
labeler.yml only had base scope labels (channel, provider, tool) matching
entire directories. The PR workflow and ci-map specs already describe
fine-grained module labels (channel:telegram, provider:kimi, tool:shell)
but the labeler config never implemented them.
Adds 27 channel, 13 provider, and 12 tool group entries. Base labels are
preserved for the compaction rule in pr-labeler.yml.
* feat(ci): add pr-path-labeler workflow to invoke actions/labeler
labeler.yml has path-label config but no workflow was invoking it.
Adds pr-path-labeler.yml on pull_request_target to apply path and
per-component labels automatically. Updates actions source policy
doc to reflect the new workflow and action.
* docs(contributing): add label registry as single reference for all PR labels
Label definitions were scattered across labeler.yml, label-policy.json,
pr-workflow.md, and ci-map.md with no consolidated view. Adds a single
registry documenting all 99 labels by category, their definitions, how
each is applied, and which automation exists vs. is specced but missing.
* docs(contributing): correct label-registry automation status
The CI was simplified from 20+ workflows to 4. Size, risk,
contributor tier, and triage label automation (pr-labeler.yml,
pr-auto-response.yml, pr-check-stale.yml) were removed during
that simplification. Update the registry to reflect that these
labels are now applied manually, not "not yet implemented."
See PR #2931 for the upstream docs cleanup.
