chore(docs): collapsible examples, dated changelogs, bot sync token

[16bit-ykiko]

What changed

• Feature-doc examples now render collapsed. tools/feature_docs.ts wraps each generated example in <details><summary>Example</summary> (plain HTML rather than VitePress's ::: details, so the collapse also works on GitHub). All six fixture-generated feature docs regenerated; item titles, status boxes and descriptions stay visible, only the code folds.
• Per-feature ## Changelog tables normalized. Every row now carries the real merge date (YYYY-MM-DD) and an inline PR link, recovered from git history; rows are reverse-chronological. — remains only in the PR column for changes predating the PR workflow. Also fixes hover's changelog date: feat(hover): port clangd hover implementation #452 merged 2026-06-12, not 2025-06.
• Docs sync switched to the bot account. The deploy job in main.yml now uses the CLICE_DOCS secret (fine-grained PAT of clice-bot) instead of PUBLISH_DOCS, so sync PRs in the docs repo no longer impersonate the maintainer. Merging this PR touches docs/** and will itself exercise the new token end to end.
• Removed docs/semantic-tokens-example.cpp, unreferenced since the tests refactor.

Tests

• All four suites pass locally (unit 1174, integration 341, smoke 3, snap 395).
• pixi run check-feature-docs, npm run check, pixi run format all clean.
• VitePress build of the docs site verified locally with the regenerated pages; the rendered HTML contains the collapsed <details> blocks.
