feat: capture Rust→server HTTP edges + fix obsidian regen and grammar guard

- enrich.py: add Rust `format!("{}/api/...")` regex so reqwest calls in
  Tauri commands resolve to backend routes; widen the API-scan node-type
  filter to include `route`/`service` so cross-language IPC→HTTP chains
  appear in the graph (e.g. `src-tauri → server` calls_api edges).
- obsidian.py: clear stale per-service `*.md` notes at the start of vault
  generation so step 5's collision branch no longer drops freshly built
  notes, which had been silently preserving outdated `## Connections`.
- base.py: `is_grammar_allowed` fallback flips from allow→deny when the
  grammar can't be identified, preventing unrelated query files (e.g.
  Python parsed against `svelte.scm`) from triggering the
  `Invalid node type: export_statement` warning.
