feat(mcp-cli): add a --format=table renderer for gittensory-mcp intelligence output

[JSONbored]

The stdio CLI only prints either raw JSON (--json) or an ad-hoc line summary (process.stdout.write loops in packages/gittensory-mcp/bin/gittensory-mcp.js, e.g. emit() at line 1349 and the analyze/preflight renderers around line 1557). There is no compact tabular output for the multi-row reports (score blockers, next actions). Add a shared, dependency-free table renderer and a --format table option for the report-shaped commands.

Deliverables

• Add a small pure formatTable(rows) helper in packages/gittensory-mcp (no new deps) with column alignment
• Accept --format table|json|text in parseOptions and route report-shaped commands through it (default text unchanged)
• Apply it to at least the analyze-branch / preflight blocker+action lists
• Unit tests for the table formatter (alignment, empty rows, wide values) and a CLI test for --format table
