Robust Hook Escaping + Auto-Context Fix

Fixed — Commands with Embedded Quotes Truncated

• JSON parser rewrite — Hook scripts and Rust handler now correctly parse JSON values containing escaped quotes (e.g. curl -H "Authorization: Bearer token"). Previously, the naive [^"]* regex stopped at the first \" inside the value, truncating the command. Now uses ([^"\\]|\\.)* pattern with proper unescape pass. Affects both bash scripts and Rust extract_json_field.
• Double-escaping for rewrites — Rewrite output now applies two escaping passes: shell-escape (for the -c "..." wrapper) then JSON-escape (for the hook protocol). Previously, only one pass was applied, causing inner quotes to break both shell and JSON parsing.

Fixed — Auto-Context Noise from Wrong Project (#62 Issue 4)

• Project root guard — session_lifecycle_pre_hook and enrich_after_read now require a known, non-trivial project_root before triggering auto-context. Previously, when project_root was None or ".", the autonomy system would run ctx_overview on the MCP server's working directory (often a completely different project), injecting irrelevant "AUTO CONTEXT" blocks into responses.

Improved — Cache Hit Message Clarity (#62 Issue 3)

• Actionable stub — Cache hit responses now include guidance: "File already in context from previous read. Use fresh=true to re-read if content needed again." Previously, the terse F1=main.rs cached 2t 4L stub left AI agents confused about what to do next.

Housekeeping

• Redirect scripts reduced to minimal exit 0 (removed ~30 lines of dead is_binary/FILE_PATH parsing code that was never reached).
• 4 new unit tests for escaped-quote JSON parsing and double-escaping.
• 1 new integration test for auto-context project_root guard.
• All 611 tests passing, zero clippy warnings.
