fix(#3229): shared model catalog source of truth for agent profiles + runtime tier defaults (#3230)

* docs(adr): add ADR-0003 model catalog module

* fix(#3229): add shared model catalog as source of truth for agent profiles and runtime tier defaults

Research / design (ADR-0003):
- Existing drift came from 4 independent model truths:
  1. CJS model-profiles.cjs
  2. SDK config-query.ts stale copy (18 agents)
  3. settings-advanced.md runtime tier table
  4. session-runner Claude-only profile map
- New design: one machine-readable Model Catalog Module in sdk/shared/
  that both packages ship and consume.

Implementation:
- sdk/shared/model-catalog.json — canonical source of truth for:
  - full 33-agent registry
  - per-agent golden (quality) alias + balanced/budget aliases
  - adaptive derivation from routingTier
  - agent→phaseType map
  - agent→dynamic-routing default tier map
  - runtime tier defaults for all supported runtimes
- get-shit-done/bin/lib/model-catalog.cjs — CJS adapter over the catalog
- sdk/src/model-catalog.ts — SDK adapter over the same catalog
- CJS model-profiles.cjs now re-exports derived data from model-catalog.cjs
- SDK config-query.ts now re-exports MODEL_PROFILES/VALID_PROFILES from
  model-catalog.ts instead of maintaining its own list
- sdk/src/query/helpers.ts runtime list now comes from the catalog (fixes hermes drift)
- sdk/src/session-runner.ts Claude profile→model-id mapping now resolves via catalog
- docs/CONFIGURATION.md + settings-advanced.md runtime tables updated to match catalog

Behavior changes:
- resolve-model now covers every shipped agent file on disk (33 agents)
- unknown-agent fallback is profile-semantic, not hardcoded sonnet:
  quality→opus, budget→haiku, balanced/adaptive→sonnet, inherit→inherit
- Group B runtimes remain known runtimes but do not get built-in tier defaults

Tests (RED→GREEN):
- root tests: shipped agent files must equal MODEL_PROFILES keys
- sdk tests: shipped agent files must equal MODEL_PROFILES keys
- direct fix assertion: gsd-code-reviewer resolves to opus under quality with no unknown_agent
- runtime defaults parity test: settings-advanced.md + CONFIGURATION.md tables must match catalog
- helper tests: hermes included in SUPPORTED_RUNTIMES and getRuntimeConfigDir()

Closes #3229

* chore(changeset): update #3229 changeset pr field to 3230

* fix(ci): update inherit fallback expectations and inventory parity for model catalog
