630a705bdc fix(gemini): use AfterTool instead of PostToolUse for Gemini CLI hooks
Gemini CLI uses AfterTool as the post-tool hook event name, not
PostToolUse (which is Claude Code's event name). The installer was
registering the context monitor under PostToolUse for all runtimes,
causing Gemini to print "Invalid hook event name" warnings on every
run and silently disabling the context monitor.

Changes:
- install.js: use runtime-aware event name (AfterTool for Gemini,
  PostToolUse for others) when registering context monitor hook
- install.js: uninstall cleans up both PostToolUse and AfterTool
  entries for backward compatibility with existing installs
- gsd-context-monitor.js: runtime-aware hookEventName in output
- docs/context-monitor.md: document both event names with Gemini
  example

Closes #750

7542d364b4 feat: context window monitor hook with agent-side WARNING/CRITICAL alerts
Adds PostToolUse hook that reads context metrics from statusline bridge file and injects alerts into agent conversation when context is low.

Features:
- Two-tier alerts: WARNING (<=35% remaining) and CRITICAL (<=25%)
- Smart debounce: 5 tool uses between warnings, severity escalation bypasses
- Silent fail: never blocks tool execution
- Security: session_id sanitized to prevent path traversal
