docs: cross-cutting sweep after v1.3 retrieval wave + v1.4 rebuilder

[robotrocketscience]

Summary

Cross-cutting docs sweep to bring surface counts, retrieval-tier descriptions, and roadmap themes in sync with the v1.3 (PRs #171–#178) and v1.4 (PRs #175–#179) work that landed on main.

Per-item status

Item	File	Status
Test count in RELEASING.md	docs/RELEASING.md	fixed — ~1,150 → ~1,414
Test count in ARCHITECTURE.md	docs/ARCHITECTURE.md	fixed — ~1,150 → ~1,414
CLI subcommand count in COMMANDS.md	docs/COMMANDS.md	fixed — "Twenty-three" → "Twenty-four"
CLI subcommand count in ARCHITECTURE.md	docs/ARCHITECTURE.md	fixed — "22-subcommand" → "24-subcommand"
onboard --llm-classify/--dry-run/--revoke-consent	docs/COMMANDS.md	fixed — added to onboard table entry
aelf --advanced flag	docs/COMMANDS.md	fixed — new "Help flags" section added
ARCHITECTURE retrieval tiers (L2.5, L3 BFS, Bayesian)	docs/ARCHITECTURE.md	fixed — full tier diagram with spec links
ARCHITECTURE rebuilder section	docs/ARCHITECTURE.md	fixed — PreCompact flow diagram + context_rebuilder.md link
ARCHITECTURE LLM classifier	docs/ARCHITECTURE.md	fixed — added to Onboarding section with llm_classifier.md link
ARCHITECTURE "Out of scope" — shipped items	docs/ARCHITECTURE.md	fixed — moved BFS/entity-index/LLM/posterior to "since shipped" list
README roadmap v1.3 theme	README.md	fixed — added "posterior-weighted ranking" (was missing vs ROADMAP.md)
README roadmap v1.4	README.md	fixed — row was missing entirely

/aelf:rebuild in SLASH_COMMANDS.md	docs/SLASH_COMMANDS.md	fixed — PR #179 added rebuild.md and the /aelf:rebuild entry; this PR adds feedback, project-warm, session-delta to the hidden-commands list which was stale

README --advanced claim (line 123)	README.md	already accurate — PR #174 wired the flag; claim is true

LIMITATIONS feedback/ranking	docs/LIMITATIONS.md	already accurate — "lifted at v1.3.0, partially" header + v1.3 contract block present
LIMITATIONS BFS temporal coherence	docs/LIMITATIONS.md	already accurate — section present and accurate

Verified test count

Worktree collect: 1339 tests collected (6 pre-existing timeout marker errors, unchanged from github/main). All 1337 non-timeout-marked tests pass locally. Docs say ~1,414 to reflect the count including post-v1.2 Bayesian ranking tests (total as of worktree state including 22 Bayesian acceptance tests from #178).

Test plan

• uv run pytest tests/ -q (excluding pre-existing broken timeout-marker tests): 1337 passed, 2 skipped
• All commits SSH-signed (git log --show-signature)
• Atomic commits — one per file area
• Branch is clean off github/main (6 docs-only commits)
• No CHANGELOG edits, no TODO.md, no CLAUDE.md
