Shell completions added; cross-agent skills install

Minor Changes

• df7dcae: feat(cli): add --paused / --no-paused flags to admin org update for the org-level ingest pause flag landed in buildinternet/releases#1064. Mirrors the existing --enable / --disable shape on admin source update; lands on the deprecated edit alias too. Pins @buildinternet/releases-api-types to ^0.20.0 so the typed fetchPaused field on UpdateOrgBody is in scope downstream. (#178)

• 21d41b2: MCP list_organizations now mirrors the remote MCP default of hiding orgs with zero indexed releases. Pass include_empty: true to see them. CLI releases org list gains --include-empty for the same opt-in. See buildinternet/releases#746.

• a4729e3: feat(cli): add shell completion support for bash, zsh, and fish. releases completion <bash|zsh|fish> prints the script to stdout; releases completion install detects the user's shell and writes the script to the conventional location, mirroring how gh ships completions. Once the matching tap formula update in buildinternet/buildinternet-homebrew-tap lands, Homebrew will install all three shells automatically — until then, brew users should run releases completion install. On interactive TTYs, a one-time stderr hint nudges users who haven't installed completions yet — silence with RELEASES_NO_COMPLETION_HINT=1.

• 5b1c5ae: feat(cli): add releases skills install for cross-agent skill installation (#187). Thin wrapper around npx skills add buildinternet/releases-cli from the open agent-skills ecosystem (vercel-labs/skills), which auto-detects ~50 supported coding agents (Claude Code, Cursor, Codex, Gemini CLI, Windsurf, GitHub Copilot, …) and writes the 8 bundled skill files to the right per-agent directory. Forwards --global, --agent <name>, --copy, --list, and --no-yes to the underlying skills add invocation. Skills are symlinked by default, so re-running the command refreshes everything atomically.

• 05f08be: feat(cli): nag when installed agent skills are behind the repo's main HEAD (#188). After a successful releases skills install, the CLI records the current skills/ tree SHA as a baseline. Subsequent invocations poll GitHub (24h cache, 2s timeout, best-effort) and print a single dim stderr line — "Your installed releases skills are behind. Run releases skills install to refresh." — when the baseline diverges. Also reads the skills CLI's lock file ($XDG_STATE_HOME/skills/.skill-lock.json or ~/.agents/.skill-lock.json) to suppress the nag when the user has clearly uninstalled via skills (lock present, zero buildinternet/releases-cli entries); manual installers and users without a lock file fall through to the existing baseline check, unchanged. Mirrors the existing CLI update-check pattern, with the same skip conditions (--help/--version, non-TTY, no baseline recorded) plus a fresh RELEASES_DISABLE_SKILL_UPDATE_CHECK=1 opt-out.

• 839ab72: Remove deprecated --notes and --parse-instructions inline flags (Phase 2 of #103).

  Both flags were deprecated in Phase 1 (#118) with file-based replacements. They are now removed; passing either flag exits non-zero with unknown option. Use --notes-file and --parse-instructions-file (or - for stdin) instead.

Patch Changes

• 5aad6aa: chore(cli): bump @buildinternet/releases-api-types to ^0.21.0 and align sourceToMarkdown with the cursor-paginated SourceDetail shape. The helper had no callers in production code; this is a types-alignment fix with zero runtime impact.
• 3b4b2a9: fix(cli): allow 0 for --min-new-releases and --min-overview-age-days in admin overview batch to match API contract (#174)
• ac18409: fix(cli): reject partial integers in parsePositiveIntFlag — "1.5" and "10abc" no longer silently truncate to 1 and 10 (#177)
