Add accepted-plan decomposition exact-once guards and UI state (#6831)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies, so
planning approvals and child-issue fan-out are part of the core
control-plane loop.
> - Accepted plans are supposed to be a safe bridge from planning into
execution, especially when agents wake from review decisions and reuse
isolated workspaces.
> - The duplicate-subtask incident showed that an accepted plan revision
could be interpreted more than once across overlapping runs, which broke
the single-source-of-truth model for issue decomposition.
> - Fixing that required tightening the backend contract first:
accepted-plan decomposition needs an exact-once fingerprint, durable
claim state, and retry-safe child creation.
> - Once that backend behavior existed, the board still needed
visibility into what happened, so the issue detail view needed a
dedicated decomposition section instead of forcing operators to
reconstruct child creation from raw activity.
> - This pull request adds the exact-once decomposition primitive,
hardens wake routing and regressions around the incident, and surfaces
decomposition state in the UI so future incidents are both prevented and
easier to inspect.

## What Changed

- Added accepted-plan decomposition semantics to
`doc/execution-semantics.md`, including the exact-once fingerprint,
durable claim/result expectations, and retry/resume behavior.
- Added persistent accepted-plan decomposition claims in the backend,
including schema, shared types/validators, service logic, and issue
routes for creating and listing decomposition state.
- Hardened heartbeat routing so an accepted-plan continuation stays
scoped to the relevant planning issue instead of opportunistically
re-decomposing another accepted issue on the same assignee.
- Added regression coverage for the original failure modes: concurrent
same-parent retries, cross-issue accepted-plan isolation, and partial
child recreation under the same fingerprint.
- Added the `Plan decomposition` issue-detail section plus supporting
API/query-key/activity formatting updates so operators can see revision
status, owner, child counts, and the linked child issues directly in the
UI.
- Included the small follow-up UI fix so the decomposition section still
renders when the issue work mode is no longer `planning`.

## Verification

- `pnpm --filter @paperclipai/server typecheck`
- `pnpm --filter @paperclipai/ui typecheck`
- `pnpm --filter @paperclipai/db typecheck`
- `pnpm exec vitest run server/src/__tests__/issues-service.test.ts`
- `pnpm exec vitest run server/src/__tests__/issues-service.test.ts -t
"lists persisted decompositions with child issue summaries"`
- `pnpm exec vitest run server/src/__tests__/issues-service.test.ts -t
"accepted plan decomposition"
server/src/__tests__/heartbeat-accepted-plan-workspace-refresh.test.ts
server/src/__tests__/heartbeat-context-summary.test.ts`
- Manual UI path: create a planning issue without an isolated execution
workspace, add a `plan` document, accept the `request_confirmation`, let
Paperclip create child issues, then reopen the parent issue detail page
and confirm the `Plan decomposition` section shows the accepted
revision, status, idempotent-claim badge, and child links.
- Separate follow-up bug noted during manual UI validation: accepting a
plan on an issue whose run never records `workspace_finalize` is tracked
in `PAPA-445` and is not part of this PR’s fix scope.

## Risks

- This adds a new migration and a large Drizzle snapshot update;
reviewers should confirm the schema shape and generated metadata match
the intended decomposition table.
- The exact-once claim changes sit on the accepted-plan fan-out path, so
regressions there could block legitimate child creation or mis-handle
retries if the claim state machine is wrong.
- The new UI only appears when decomposition records exist; reviewers
should use the manual verification path above rather than expecting
existing issues on a stale local instance to show the section
automatically.
- `PAPA-445` remains an open follow-up for the `workspace_finalize`
accept gate when a planning handoff never records finalize; that bug can
interfere with reproducing the UI flow on isolated workspaces but does
not change the correctness of the exact-once decomposition feature
itself.

> Checked `ROADMAP.md`: this PR is a bug fix / control-plane hardening
change for accepted-plan decomposition, not a new uncoordinated roadmap
feature.

## Model Used

- OpenAI Codex via Paperclip `codex_local` (GPT-5-based coding agent;
exact backend model ID/context window not exposed in the run context),
with repository tool use, shell execution, and code-editing
capabilities.
