release: v0.6.0 — Sigma graph, parallel metrics, dead-code accuracy, workspace fixes

[RaghavChamadiya]

Summary

First release since v0.5.1 (2026-05-07). Eleven PRs land here — no breaking changes, no API surface freeze, so this is a minor bump.

Highlights:

• Sigma.js graph renderer replaces React Flow as the primary view (Review fixes, health score breakdown, module grid collapse #148). FA2 force layout + ELK hierarchical share one canvas; full parity for inspection, search, communities, execution-flow, drill-down, and signal overlays.
• Per-phase progress for graph build + metrics (feat(progress): decompose graph build into reportable sub-phases #150). The "0/1 spinner for 5–10 minutes" problem is gone — six indented bars now.
• Parallel metrics computation (perf(graph): fan out metrics computation in parallel #152). PageRank, betweenness, communities, and execution flows run via asyncio.gather + asyncio.to_thread and cache on GraphBuilder.
• Tree-sitter query cache promoted to module-level lru_cache (perf(parser): cache compiled tree-sitter queries at module level #154). Workers compile each grammar's queries once for their lifetime instead of once per parser instance.
• Python relative-import binding bug fixed (fix(ingestion+mcp): relative-import binding bug + audit-driven UX/MCP fixes #149). from .X import Y was dropping Y; this caused massive dead-code false positives on Repowise's own source. Regression coverage added.
• Dead-code unused-export false positives fixed (fix(dead-code): drop residual unused-export false positives #153). Decorator persistence + @-prefix matching + nested-def skip.
• repowise update mode persistence (fix(update): persist init mode + lock-file suppression for stale-wiki hook #155). state.json now stores docs_enabled; the post-commit hook does the right thing without extra knobs. Stale-wiki warning is no longer per-tool-call spam.
• Cost-gate state migration + UX (fix(release): state migration safety + cost-gate UX #156). Legacy index-only state files no longer accidentally trigger a full LLM regen on first upgrade. Decline now produces a clean index-only outcome (work persisted, future updates default to index-only). Prompt is visually separated from Rich output.
• Workspace chat 404 fix (fix(chat): route /api/repos/{repo_id}/chat/messages by workspace_sessions #146). POST /api/repos/{repo_id}/chat/messages now routes by workspace_sessions.
• gitpython 3.1.47 → 3.1.50 (chore(deps): bump gitpython from 3.1.47 to 3.1.50 #147) — security release.

Validation

• Version bumped in all four files + uv.lock (no stale 0.5.1 references).
• uv build --wheel produces dist/repowise-0.6.0-py3-none-any.whl cleanly.
• Wheel structure: 19 commands under cli/, 15 .scm tree-sitter queries, 12 .j2 templates, top-level packages cli/core/server.
• Wheel installs cleanly into a fresh venv and repowise --version reports 0.6.0.
• repowise.cli.__version__, repowise.core.__version__, repowise.server.__version__ all report 0.6.0.
• CI green on all 11 contributing PRs.
• Reviewer: verify npm run build --workspace packages/web succeeds (Sigma migration + types/ui workspace deps).
• Reviewer: end-to-end smoke test (repowise serve) — graph, hotspots, blast-radius, wiki, decisions, costs.
• Post-merge: tag v0.6.0 on the merge commit and push to trigger publish.yml.

Merge convention

Per .claude/RELEASING.md, this is a regular merge commit (not squash) so main keeps the per-PR commit history.
