* chore(compat): date the annotated deprecation families and expose removal-pending debt
Adds 10 dated compat-registry records for shipped deprecated surfaces that
previously had @deprecated annotations only (removeAfter 2026-10-01 per the
approved 60-day window), extends the beta5 session-store record with the
package-root aliases, surfaces removal-pending records with due dates,
blockers, and readers in the plugin boundary report, and converts undated
cleanup obligations (CI timing job, zizmor excessive-permissions, staged
Codex CI auth, memory-host legacy state dir, agent-DB schema-ladder floors)
into dated markers visible to the weekly dated-TODO sweep. Metadata,
diagnostics, and docs only - no runtime behavior change.
* fix(compat): keep extension src test paths out of core string literals
The core import guardrail forbids extensions/*/src/ path shapes in core
production string literals; cite the package-root google-meet test and the
registry test for official-plugin-export-aliases instead.
* feat(tooling): add tsgo typecheck lane for scripts/**
* fix(scripts): burn down scripts type debt surfaced by the new lane
Typing-only except bugs the lane surfaced: gh-read timeout race,
Discord Headers spread dropping entries, undefined allowedHeadBranches
match, plugin-boundary matchAll crash. Deletes retired config keys from
fixtures/benches (prompt snapshots regenerated, config dump only) and
the orphaned non-runnable sync-moonshot-docs script. Adds full-surface
.d.mts declarations for existing .mjs boundaries.
