install: wire ui-input-guard and hook-freshness into the inventories

[EdbertChan]

Both hooks join install.sh (link plus settings merge), the README hook table,
the ecosystem ownership table, and test_install's per-hook link and event
assertions.

Depends-On: #293

---

Note

Low Risk
Documentation and install/test wiring only; hook behavior lives in separate hook packages (depends on #293).

Overview
Wires ui-input-guard and hook-freshness into the standard install path so they ship with ./install.sh, not only as hook directories in the repo.

install.sh now symlinks ui-input-guard into Claude, Cursor, and Codex hook dirs, and hook-freshness into Claude only. It also runs each hook’s install_claude_hook.py so Claude settings.json gets PreToolUse for ui-input-guard and UserPromptSubmit for hook-freshness. The README hooks table and docs/ecosystem.md inventory list both hooks with their behavior summaries.

tests/test_install.py adds the usual per-hook assertions: symlink targets and the correct Claude event wiring for each hook.
