v0.34.0

Added

• Report documentation site. tools/docs-site.sh serves a project's reports/ tree as a
  local, searchable documentation site on Blume (Astro; Node ≥ 22.12):
  one page per report with Mermaid rendered, the OpenAPI / AsyncAPI specs mounted as Blume's API
  reference (/api/<service>, /events/<name>), the consolidated full-report.html served
  as-is, and a landing page built from work/pipeline-progress.json (options, every phase with
  its status and links to its outputs). sync, dev (re-syncs as reports/ changes), build,
  preview, validate (internal links), clean. Nothing in reports/ is modified: the site is
  a stage rebuilt on every run, and every generated directory under tools/docs-site/ is
  git-ignored.
• tools/docs-site/sync_reports.py — the conversion: reports become MDX (Blume renders Mermaid
  only in .mdx); {…} and a bare < outside code are escaped; numeric phase prefixes are
  dropped from routes (01_analysis/x.md → /analysis/x) so cross-report links can be
  rewritten; links to project files the site cannot serve (samples/…, work/context.md)
  become plain text; each report's own frontmatter is kept under a declared nexus key (Blume
  rejects unknown keys and its built-in id / status collide with the ADR shape); top-level
  directories are sidebar groups in pipeline order, pages inside follow the manifest's
  declared-output order.
• docs/docs-site.md (+ _ja), with pointers from README, docs/getting-started and CLAUDE.md.
