slash-commands: gate project status update on a required PR label

Browse source 
Add project-gate-label input. When set, the project status update on
/lgtm accept only runs if the PR carries that label — lets callers
restrict project-board tracking to a subset of PRs (e.g. only SEPs go
to the SEP Review Pipeline, not every accepted PR).

onAccept now takes the full PR object instead of (number, nodeId) so it
can inspect labels without a second fetch.

Label removal via remove-labels-on-accept is unchanged — it runs on
every accept regardless of the gate.
