feat(framework/tools): orchestration helpers — lane-brief.sh + ci-wait.sh (#546)

Two additive orchestration tools distilled from forensic analysis of a live
U-Connect delivery session, both adopted by the live orchestrator before this
contribution.

lane-brief.sh (git/): one call returns the CURRENT open issue set for a repo
lane (milestone/label) from Gitea, classified for dispatch. Defeats stale
worker self-report (workers brief from static notes and report already-CLOSED
issues as "todo"). Closed excluded by definition; partitions by PR-linkage
(reliable) not assignee/dependency (empty in this fleet). Login resolution:
-L > $GITEA_LOGIN > owner inference > detect-platform.sh fallback.

ci-wait.sh (woodpecker/): blocks until pipeline(s) reach terminal state,
wrapping pipeline-status.sh (resolves repo->id, instance-aware). Replaces
hand-rolled `curl .../repos/1/pipelines/$n` loops that hardcode repo id 1.
Intended as a Monitor command + long (>=1500s) timed fallback, not a tight
poll. Exit 0=all success / 1=terminal non-success / 2=usage / 3=timeout.

Tested live vs usc/uconnect. README updated. No version bump (separate
release PR per convention).
