rtk aws and rtk psql modules exist since PR #216 but were missing
from the registry rules — rewrite was silently skipping them.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Cover all command categories added in PR #241 and missing from
the previous test suite:
- aws / psql (PR #216 modules, gap detected during non-reg run)
- Python: ruff, pytest, python -m pytest, pip, uv pip
- Go: go test/build/vet, golangci-lint
- JS/TS: vitest, pnpm vitest, prisma, prettier, pnpm list
- Compound operators: || and ; rewrites, 4-segment chains,
  mixed supported/unsupported segments, all-unsupported → None
- sudo prefix rewrite, env var prefix rewrite
- find with native flags
- Registry invariants: PATTERNS/RULES aligned, all rules valid,
  all patterns are valid regex

Before: 559 tests. After: 607 tests.

Adds aws_cmd, psql_cmd (PR #216) and rewrite_cmd (this PR) to the

* feat: add `rtk rewrite` command — single source of truth for hook rewrites

Implements `rtk rewrite <cmd>` as the canonical rewrite engine for all
LLM hook integrations (Claude Code, Gemini CLI, future tools).

- Add `rewrite_prefixes` field to `RtkRule` in discover/registry.rs
- Add public `rewrite_command()` with compound command support (&&, ||, ;, |)
- Add `rewrite_segment()`, `rewrite_compound()`, `strip_word_prefix()` helpers
- Handle already-rtk commands (exit 0, identical output)
- Handle unsupported/ignored commands (exit 1, no output)
- Add 20 unit tests covering all branches and edge cases
- Create `src/rewrite_cmd.rs` thin CLI wrapper
- Register `Commands::Rewrite` in main.rs
- Simplify `.claude/hooks/rtk-rewrite.sh` from 357 → 60 lines

Hooks no longer need duplicate mapping logic — a single
`REWRITTEN=$(rtk rewrite "$CMD") || exit 0` handles everything.

* docs: fix version references and module count for 0.22.2

- README.md, CLAUDE.md, ARCHITECTURE.md: 0.20.1 → 0.22.2
- ARCHITECTURE.md: module count 48 → 51 (added rewrite_cmd + 2 from master)

* ci: update hook coverage check to verify registry (not hook script)

Since PR #241, the hook delegates to `rtk rewrite` — command mappings
live in src/discover/registry.rs, not the bash hook script.

Update the "Verify hook coverage" CI step to:
- Check that the hook calls `rtk rewrite` (new architecture)
- Check that registry.rs has rewrite_prefixes for all Python/Go commands

* feat: support single `&` background operator in compound rewrites

Per feedback from @xDelph: AI agents increasingly use `cmd1 & cmd2`
for parallel execution. This commit adds support alongside existing
`&&`, `||`, `;`, and `|` operators.

Changes:
- rewrite_compound: add match arm for single `&` (after `&&` check)
- rewrite_command: add `" & "` to has_compound detection
- init: show "installed/updated" vs "already up to date" so users
  know whether rtk init changed the hook on re-run

* fix: add Python/Go commands to rewrite registry

Add `ruff`, `pytest`, `pip`, `go`, and `golangci-lint` to both
PATTERNS and RULES in registry.rs so the CI coverage check passes
and `rtk rewrite` correctly identifies these commands.

* fix: address P0 review feedback on rtk-rewrite PR

P0.1 - Replace 218-line bash hook with 58-line thin delegating hook.
  All rewrite logic now lives exclusively in `rtk rewrite` (Rust registry).
  `rtk init` installs the thin hook via include_str!.

P0.2 - Fix `head -20 file` crash at runtime.
  Generic prefix replacement produced `rtk read -20 file` (invalid clap args).
  Now translates `head -N file` → `rtk read file --max-lines N` and skips
  unsupported head flags (e.g. -c) by returning exit 1.

P0.3 - Add version guard in hook for rtk < 0.23.0.
  Prints a warning to stderr instead of silently doing nothing.

Also adds missing registry entries vs old hook:
  - gh release, cargo install
  - docker run/exec/build, kubectl describe/apply
  - tree, diff

474 tests pass, 0 clippy warnings.

* refactor(discover): extract rules/patterns into rules.rs

Per aeppling review: registry.rs was too large (~1500 lines).
Extract all static data into src/discover/rules.rs:
- RtkRule struct (with pub fields)
- PATTERNS const array
- RULES const array
- IGNORED_PREFIXES and IGNORED_EXACT const arrays

registry.rs now contains only logic + tests.
rules.rs is the single place to add a new command mapping.

* feat(migration): document breaking change + detect outdated hook in rtk config

CHANGELOG [Unreleased]:
- Migration required: rtk init --global needed after upgrade
- Documents upgrade path and explains no immediate breakage

rtk init --show / rtk config now detects old hook (inline if-else)
vs new thin delegator (rtk rewrite) and prints actionable warning:

  ⚠️  Hook: ~/.claude/hooks/rtk-rewrite.sh (outdated — inline logic, not thin delegator)
     → Run `rtk init --global` to upgrade to the single source of truth hook

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* docs: update hook references for thin delegator (0.24.0)

- ARCHITECTURE.md: fix hook description (shell script → thin delegator)
- INSTALL.md: add upgrade path for old hook users (pre-0.24 breaking change)
- SECURITY.md: add registry.rs + hook files to Tier 1 critical files

* ci: fix hook coverage check to search rules.rs instead of registry.rs

After the PR #241 refactor, rewrite_prefixes constants moved from
registry.rs to rules.rs. Update grep to search the whole discover/
directory so it finds them in the right file.
