peter 5ca2a0e6ee fix(gate): the plan-code guard catches bare sprint and phase codes, and the purge takes the P ones
The sprint alternative matched only `(S6)` or `S3e2`, so the commonest purged form (`# S6:`,
`S3's`, `"""S6 —`, `S1 justified`) and every phase code (`P1`) would come back unflagged; the phase
codes had in fact survived the purge in 16 lines (Plex client sections, the upload's header shape),
now reworded around them.

One pattern now covers epic, roadmap, sprint and phase codes; the named exceptions are TV episode
notation, a fixture's season or episode title (`title="S1"`) and ruff's `E4/E7/E9`, and a ruff rule
like `S110` does not match. The case test lists the purged forms and no longer claims every form.
audit_metrics copies the definition (ASCII, as JavaScript's \b is) and reports it as
plan_code_lines / plan_code_files.

"""The codebase's health numbers in one deterministic run: size, complexity, tests, governance
weight, comment noise and the footprint of features marked for removal. It REPORTS, it never fails
— what used to be a gate (the size/complexity ratchet) is read here instead, and an epic compares
its before and after.
python scripts/audit_metrics.py the static numbers (seconds), as JSON on stdout
python scripts/audit_metrics.py --speed plus the speed baseline: frontend/e2e/speed.measure.ts
against the localdev stack (E2E_PASSWORD must be set;
the ops wrapper exports it)
The readings are counts of files and lines, so a number moves only when the code does.
