Workspace DB canonical schema v0 design を schema-v0.md artifact と workspace-server SQLite bootstrap/migrations に整合させ、Orchestrator worktree の orchestration branch に統合した。

主な成果:

• SQLite schema version を 2 に進め、canonical schema v0 を実装。
• Typed v0 tables を追加:
  • tickets
  • ticket_events
  • ticket_relations
  • objectives
  • objective_ticket_links
  • repositories
  • ticket_targets
  • ticket_target_paths
  • ticket_worker_links
  • artifacts
  • audit_events
• Canonical v0 から top-level runs, hosts, workers, actors, validation/CI result tables を除外。
• Generic metadata_json, payload_json, diagnostics_json のような catch-all payload columns を canonical v0 tables に追加しない方針を維持。
• /api/runs と frontend Runs card/reference を削除し、404 test を追加。
• Host/Worker APIs は DB authority ではなく live runtime views として維持。
• Legacy bootstrap tables は non-canonical legacy_* preservation tables に demote。
• Legacy workspaces は legacy_workspaces に preserve し、active canonical workspaces を v0 column set で作り直して既存行を copy。
• Post-upgrade upsert_workspace() for new workspace id が通る regression test を追加。
• schema-v0.md に SQLite version 2 / legacy preservation alignment notes を追加。

統合・検証:

• Merge commit: 38bd122d merge: workspace db schema v0
• Implementation commits: 5149ab70, d89ace5b
• Reviewer final verdict: approve
• Validation passed: cargo fmt --check, git diff --check HEAD^1..HEAD, cargo test -p yoi-workspace-server, cargo check -p yoi-workspace-server, deno task check, deno task build, cargo run -p yoi -- ticket doctor, and nix build .#yoi --no-link。

範囲外:

• Ticket/Objective write authority migration to DB is not implemented。
• Host/Worker canonical DB tables are not added。
• Validation/CI result tables and Actor table are not added。
• Full TicketEvents/TicketWorkerLinks/Artifacts write surfaces are not implemented beyond schema/bootstrap alignment。
