Add OpenAI interface metadata to 14 skills (commit-staged,
implement-isolation, implement-isolation-tmux, project-context-pack,
setup-skills, agent-handoff, knowledge-gardener, tmux-launch-agent,
conversation-summary, crit, pkm-curation, research-vault,
youtube-video-capture, lsp-code-analysis).
Add new lsp-code-analysis skill for semantic code navigation and
refactoring via the Language Server Protocol.
Replace the monolithic implement-issue and implement skills with two
focused alternatives: implement-isolation (subagent + reviewer) and
implement-isolation-tmux (tmux-launch-agent for fire-and-forget).
Update the README to list the new skills.
