docs: skill tool/perm + parent keybind

[opencode-agent]

Doc Updates Needed (and Done)

• Native skill tool + permission controls (feat: add native skill tool with permission system): added/updated docs in:
  • packages/web/src/content/docs/skills.mdx:1 (updated discovery rules, required frontmatter, new permission examples, updated <available_skills> format)
  • packages/web/src/content/docs/permissions.mdx:1 (documented permission.skill including wildcard rules)
  • packages/web/src/content/docs/tools.mdx:1 (added built-in skill tool section)
• TUI subagent navigation (feat(tui): go to parent keybind for subagents): documented new session_parent keybind in:
  • packages/web/src/content/docs/keybinds.mdx:1

Already Documented

• Typst LSP support (feat(lsp): add Tinymist LSP support for Typst) is already reflected in packages/web/src/content/docs/lsp.mdx:1.

Skipped (Not Doc-Worthy / No Good Home Yet)

• Desktop “review pane toggle” (feat(desktop): review pane toggle): user-facing, but there isn’t currently a dedicated Desktop docs page to put it in (docs largely cover TUI/CLI/IDE extension). Happy to add a small Desktop section somewhere if you want.
• TUI layout/styling tweaks and other internal changes: no docs needed.

Validation

• packages/web docs build (bun run build) succeeds.

No new doc pages were created, so packages/web/astro.config.mjs didn’t need changes.
