docs(rtk): update RTK coverage from v0.16.0 to v0.28.0

New modules: docker compose, mypy, aws, psql, cargo nextest, Graphite CLI (gt), wc.
Major features: TOML Filter DSL (declarative filters, 33+ built-in, no Rust required),
rtk rewrite single source of truth (migration note: rtk init --global after upgrade),
rtk gain -p per-project savings, rtk init --global settings.json auto-patch,
exclude_commands config, SHA-256 hook integrity.

Updated: ultimate-guide.md, third-party-tools.md, reference.yaml (version_tested bump).

 - Use both together for maximum efficiency

+**TOML Filter DSL (v0.28.0 — add filters without writing Rust):**
+
+RTK now supports a declarative filter engine via TOML config. You can add custom output filters for any command without touching Rust code.
+
+```toml
+# .rtk/filters.toml (project-local) or ~/.config/rtk/filters.toml (user-global)
+
+[[filters]]
+match_command = "my-build-tool"
+strip_lines_matching = "^(DEBUG|TRACE|INFO):"
+max_lines = 50
+```
+
+Lookup chain: `.rtk/filters.toml` (project) → `~/.config/rtk/filters.toml` (global) → 33 built-in filters (brew, poetry, dotnet, swift, uv, tofu, ansible, helm, etc.)
+
+Available primitives: `strip_ansi`, `replace`, `match_output`, `strip/keep_lines_matching`, `truncate_lines_at`, `head/tail_lines`, `max_lines`, `on_empty`
+
+Debug: `RTK_NO_TOML=1` bypasses all TOML filters. `RTK_TOML_DEBUG=1` shows which filter fires.
+
 **Integration Strategies:**
 
 1. **Hook-first install** (recommended):
    ```bash
-   rtk init  # Sets up PreToolUse hook automatically
+   rtk init --global  # Sets up PreToolUse hook + patches settings.json automatically
    ```
 
 2. **CLAUDE.md instruction** (manual wrapper):

+**Configuration Options:**
+
+```toml
+# ~/.config/rtk/config.toml
+exclude_commands = ["my-interactive-tool", "fzf"]  # Never rewrite these
+```
+
+**Migration Note (v0.25.0+):**
+
+After upgrading from v0.24.0 or earlier, run `rtk init --global` to install the new thin-delegator hook. The old hook still works, but won't pick up new command mappings automatically.
+
+```bash
+cargo install rtk          # Upgrade binary
+rtk init --global          # Replace hook with thin delegator

 - ✅ **Use RTK**: Full-stack projects (JS/TS, Rust, Python, Go), testing workflows, analytics
