v0.1.50

Added

• Git repository support in okf serve — Serve any remote repo directly without manual clone. okf serve https://github.com/user/repo.git@main clones to ~/.cache/okf/repos/. Supports @ref (branch/tag/commit), --update (re-fetch), HTTPS/SSH/bare URLs. Deterministic cache via SHA256.
• --generate flag for okf serve — Auto-run okf generate if okf_bundle/index.md is missing. Only on first clone, never on --update. Opt-in (default off) — preserves serve's fast static identity.
• .okfignore / .gitignore / .okf-exclude support — Gitignore-format pattern matching across the entire pipeline. New okf/ignore.py module (~100 lines, zero deps). Supports *, **, ?, ! negation, trailing / for dirs, leading / for anchored, # comments. Integrated into generate, update, --watch, and serve.
• Homepage enhancements — "What's New" ribbon, dedicated Git feature showcase with terminal mockup, architecture diagram (Source→AST→Bundle→LSP/LLM→MCP), Before/After developer workflow comparison, CLI table regrouped by workflow categories.
• 23+30 tests — tests/test_ignore.py covers pattern matching, integration, git URL parsing, --generate logic.

Fixed

• okf/serve.py — Better error message when git ref doesn't exist.
• okf/serve.py — Removed extraneous f-strings.

Infrastructure

• All docs updated: CLI reference (docs/user-guide/cli-reference.md), landing page (docs/index.html), MCP card (docs/index.md).
• Issues #2 (git URLs) and #3 (.okfignore) closed as implemented.
