feat: add project summary sidebar

[harshitsinghbhandari]

Summary

• add a durable daemon-owned Project Summary projection in migration 0142 with a separate source watermark
• generate a running narrative through the project orchestrator provider using verified Codex or Claude noninteractive CLI invocation
• serialize refreshes, preserve unchanged prose through the update prompt, and advance the watermark only after valid output
• retain the last good narrative and surface provider, authentication, or generation failures
• consume delivery-independent report facts through a narrow Summary-owned read interface, including needs-input reports and opaque outputs
• add a responsive right sidebar with compact counts, decisions, outputs, freshness, navigation, and composer seed without sending

Tests

• go test ./internal/service/projectsummary
• go vet ./internal/service/projectsummary ./internal/daemon
• renderer ProjectSummaryPanel, localization coverage, and catalog tests
• npm run api
• focused SQLite migration tests

Invocation verification

• Codex 0.154.0 completed the noninteractive output probe successfully
• Claude accepted the print-mode invocation and returned the expected local organization authentication error, which the summary service surfaces while retaining the last good narrative

Integration boundary

Report delivery PR #5064 owns report schema, persistence, delivery, and report.Service.ListProject. This PR does not copy those symbols or migrations and never claims, acknowledges, wakes, interrupts, or dereferences report outputs. Its report consumer logic is independently tested behind a Summary-owned ReportReader. After #5064 lands, the remaining integration is a narrow adapter and daemon wiring from report.Service.ListProject into that reader.
