fix(autoCombo,sse): catalog hygiene — retire dead FITNESS_TABLE rows, fix 7 BUILT_IN_ALIASES targets, add model-lifecycle gate (#11503) (#11507)

Validated in a combined 4-PR batch worktree off release/v3.8.51 tip. This PR's diff overlapped taskFitness.ts and autoCombo.test.ts with the already-merged #11492/#11506 — git's merge auto-resolved both hunks cleanly (non-overlapping layers: #11492/#11506 touch layer 2 arena lookup, this PR touches layer 4 static-table hygiene); verified no conflict markers remained and re-ran the full suite after boarding.
- npm run check:model-lifecycle — PASS, 68 retired ids, 1327 catalog ids, 0 violations (re-ran with the correct `node --import tsx/esm` loader after an initial bare-node invocation mistakenly failed on path-alias resolution — that was my invocation error, not the gate)
- Focused tests: fitness-table-hygiene-11503.test.ts, taskFitness-pattern-order-8603.test.ts, model-deprecation-aliases-11503.test.ts, check-model-lifecycle-gate.test.ts, model-deprecation.test.ts, autoCombo.test.ts — part of batch's 126/126 vitest + 246/246 node:test runs
- typecheck:core, file-size, changelog-integrity, complexity, cognitive-complexity, check:cycles — all OK
- Full-repo lint: 228 problems remaining, all pre-existing dashboard react-hooks/* findings unrelated to this diff (zero errors in any file this PR touches)

Thanks for this — genuinely thorough methodology (segment-boundary matching, provider-scoped alias guard, offline lifecycle gate with a documented burn-down list for the 6 remaining catalog offenders).
