refactor: shared agent workflows (F01) and one application registry (F02)

Checkpoint for the 2026-09-11 project review remediation. Work by a previous
agent that ran out of context; committed unchanged as a rollback point before
the remaining findings land on top of it.

F01 — the two agent directories had drifted into different processes
- Six shared workflows under `resume_builder/reference/workflows/`; both
  `.agents/skills/` and `.claude/skills/` are now thin entrypoints that route
  to the same file instead of carrying full copies.
- The `.claude` copies were the stale side: fixed bullet line variants and
  character budgets that the newer process had already dropped. Removing them
  is the point of the change, not collateral.
- Parity/link regression test added; corrected the top-level file map, which
  pointed at a directory that does not exist.

F02 — application status was stored in four places and disagreed
- New registry `job_scout/state/applications.json` (26 records) with
  `application_records.py` (schema, validation, transactional write) and
  `application_tracker.py` (add/update, no quota).
- AGENTS.md and CLAUDE.md no longer keep their own status tables; both point
  at `current_applications.md`, generated from the registry.
- Interview-reached is now independent of outcome, so a withdrawal after an
  interview can record both facts. The old tables are preserved verbatim in
  `job_scout/state/history/application_status_before_2026-09-11.json`.

Verification: `python -m unittest discover -s tests -v` — 18/18 pass.
Spot-checked that the detailed SBB and Kdo Cy notes survived the migration
into the registry rather than being flattened.

Known unresolved, deliberately not invented (see FIX_PROGRESS.md):
Aker BP's application date and its Adjacent-despite-79 classification.
