lukaszraczylo 7bdb523106 fix(ci): sync ui/package.json.tpl with upgraded frontend deps
GoReleaser (.goreleaser.yaml before-hook) and the Makefile regenerate
ui/package.json from ui/package.json.tpl at build time, then run npm ci.
The deps upgrade updated ui/package.json and the lockfile but not the
template, so the release hook regenerated package.json with the old deps
and npm ci failed against the new lockfile. Sync the template to the
upgraded versions (Vite 8, Tailwind 4, vis-network 10, FontAwesome 7,
TypeScript 6, ...). Verified by replaying the hook locally: regenerate
from the template then npm ci + build both pass.

lukaszraczylo abd34c9629 fix(ci): resolve @fortawesome/fontawesome-free from public npm registry
The frontend deps bump regenerated ui/package-lock.json with the
@fortawesome/fontawesome-free tarball resolved from npm.fontawesome.com
(per the developer's scoped ~/.npmrc), which requires auth. CI has no
FontAwesome token, so `npm ci` failed with E401.

The free package is also published to the public registry with an
identical tarball/integrity, so pin @fortawesome to registry.npmjs.org
via ui/.npmrc and repoint the lockfile. Verified `npm ci` + build now
succeed with no token.

lukaszraczylo 5fe25e9328 chore: upgrade ui and docs frontend dependencies to latest
ui: Vite 8, vue-tsc 3, TypeScript 6, @vitejs/plugin-vue 6, vis-network 10,
vis-data 8, FontAwesome 7, @types/node 25. docs: Vite 8, plugin-vue 6.
Both migrated to Tailwind CSS v4.

- Tailwind v3 -> v4: @import "tailwindcss" with @theme/@config, switch to
  @tailwindcss/postcss, drop autoprefixer (bundled via Lightning CSS).
- docs: move theme into @theme, delete tailwind.config.js, remove stale
  pnpm-lock.yaml (npm/package-lock.json is authoritative).
- ui: TypeScript 6 removes deprecated tsconfig baseUrl; no code changes
  needed for vis-network 10 / FontAwesome 7.
- Bump CI Node 20 -> 22 (Vite 8 requires Node ^20.19 || >=22.12).

0 npm audit vulnerabilities; ui type-check and both production builds pass.

lukaszraczylo b7b82ce22f fix: bound SQLite WAL growth and prevent worker hangs (#49)
The worker's SQLite WAL could grow unbounded (observed 19MB) and wedge the
DB, hanging Claude Code on every prompt. No checkpoint ever truncated the
WAL (only PASSIVE auto-checkpoint, which cannot reclaim the file), the
connection-scoped pragmas were set via a single Exec so only one pooled
connection received them (e.g. busy_timeout=0 on the rest), and the
maintenance service that would optimize/checkpoint was never wired up.

- Register a sqlite3 ConnectHook driver so all pragmas (busy_timeout,
  journal_mode, synchronous, cache_size, foreign_keys, journal_size_limit)
  apply to every pooled connection; enable safe connection recycling.
- Add Store.Checkpoint (TRUNCATE), checkpoint-on-Close, and a periodic
  size-gated checkpoint loop with configurable interval/threshold.
- Wire up the previously-dead maintenance service; make trigger_maintenance
  actually run DB maintenance instead of only recalculating scores.
- Harden the user-prompt hook to honor its deadline and fail open so a
  slow worker can never stall a prompt.
- Add regression tests for WAL truncation, checkpoint-on-close, and
  per-connection pragmas.

{ question: 'Will it confuse Claude with wrong context?', answer: 'No. Mnemonic uses project isolation and semantic relevance scoring. Only memories from the current project (or global best practices) are injected, and only when they\'re actually relevant to your prompt.' },

{ question: 'How does hybrid vector storage work?', answer: 'LEANN-inspired selective storage: frequently-accessed "hub" observations (identified by access patterns and graph centrality) store embeddings. Infrequently-accessed observations recompute embeddings on-demand during search. This reduces storage by 60-80% with minimal latency impact (<50ms).' },
{ question: 'Can I delete or edit memories?', answer: 'Yes. The web dashboard at localhost:37777 lets you browse, search, edit, and delete any memory. You can also view graph relationships, storage metrics, and performance analytics. You\'re always in control.' },
{ question: 'Does it work with my existing Claude Code setup?', answer: 'Yes. Mnemonic installs as a Claude Code plugin with hooks. Your existing workflows, settings, and shortcuts remain unchanged.' },
{ question: 'What if I switch between projects frequently?', answer: 'That\'s the point. Each project has isolated memories. Switch from your Python ML project to your TypeScript app - context switches automatically.' },
{ question: 'Is there a performance impact?', answer: 'Minimal. The Go worker is lightweight (typically under 30MB RAM). Hybrid storage and auto-tuning optimize for your workload. Context injection at session start takes milliseconds for most projects.' },
{ question: 'What is AST-aware chunking?', answer: 'When processing code observations, Mnemonic uses Tree-sitter parsers to respect function and class boundaries instead of arbitrary line limits. Go, Python, and TypeScript code is chunked at semantic boundaries for better search accuracy.' },
{ question: 'Will it confuse Claude with wrong context?', answer: 'Project isolation and semantic relevance scoring prevent that. Only memories from the current project (or global best practices) are injected, and only when relevant to your prompt.' },
{ question: 'What gets stored?', answer: 'Bug fixes with context, architecture decisions, project conventions, security patterns — things you\'d otherwise re-explain each session. No raw conversation dumps.' },
{ question: 'Can I delete or edit memories?', answer: 'Yes. The dashboard at localhost:37777 lets you browse, search, edit, and delete anything. You can also view graph relationships and storage metrics.' },
{ question: 'Performance impact?', answer: 'The Go worker uses ~30MB RAM. Context injection at session start takes milliseconds for most projects. Hybrid storage auto-tunes for your workload.' },
{ question: 'Does it work with my existing setup?', answer: 'Yes. Installs as a Claude Code plugin with hooks. Your workflows, settings, and shortcuts stay the same.' },
{ question: 'What if I switch between projects?', answer: 'Each project has isolated memories. Switch from your Python ML project to your TypeScript app — context switches automatically.' },
