Fixes #1991

Makes the implicit recursive Pause/Resume cascade opt-in via ?cascade=true query parameter. Without the flag, only the named workspace is paused/resumed; with the flag, the full descendant subtree is collected via WITH RECURSIVE descendants and processed.

Caller-impact assessment (CEO Assistant ruling)

Grep across molecule-ai org identified live callers that depend on implicit cascade and will break with 409 Conflict if this PR merges as-is:

Caller	Location	Impact
Canvas ContextMenu	canvas/src/components/ContextMenu.tsx	Single-node pause/resume on parent workspaces fails
Canvas batch pause	canvas/src/store/canvas.ts	Batch pause of selected parent workspaces fails
MCP server (mgmt)	molecule-mcp-server/src/tools/management/index.ts	pause_workspace / resume_workspace tools fail
MCP server (ws)	molecule-mcp-server/src/tools/workspaces.ts	pause_workspace / resume_workspace tools fail

Branch B executed: migrate callers FIRST, keep #2122 on HOLD until follow-ups merge.

Merge dependency chain

1. PR #2264 (molecule-core) — Canvas frontend ?cascade=true migration
2. PR #40 (molecule-mcp-server) — MCP server ?cascade=true migration
3. This PR (#2122) — can merge only after #2264 and #40 are on main

Test plan

• Unit tests cover both cascade=true and default (non-cascade) paths
• Response field paused_count / resumed_count correctly reflects affected workspace count
• Follow-up PRs #2264 and #40 merged and deployed

fix(workspace): make Pause/Resume cascade opt-in via ?cascade=true ... 22ee2b0e73

POST /workspaces/:id/pause and /resume currently implicitly cascade to
all descendants. This caused incident internal#722 where a single Pause
call terminated 5 EC2-backed workspaces.

Change default behavior to single-workspace scope. If descendants exist
and cascade=true is not set, return 409 Conflict with a descendants
list so the caller can decide. ?cascade=true preserves the old
recursive behavior.

- Pause: check c.Query(\"cascade\") before stopping descendants
- Resume: mirror Pause's cascade contract
- Update TestPause_WithDescendants to use ?cascade=true
- Add 4 new tests covering 409 + 200 paths for both handlers

Fixes #1991

5-axis review: APPROVED.

Correctness: This makes pause/resume cascade behavior explicit: parent workspaces with eligible descendants now return 409 unless the caller passes ?cascade=true, while ?cascade=true preserves the prior recursive pause/resume behavior. The tests cover no-cascade conflict and cascade success for both pause and resume.

Robustness: The response includes descendant IDs/names so callers can make an informed cascade retry. Existing descendant query errors still fail normally rather than silently partial-applying. Security: no auth or secret handling changes. Performance: the recursive descendant query already existed; the added list construction is bounded by the same result set. Readability: the new branches are localized and the tests make the new contract clear.

Required-context review: head 22ee2b0e73 is mergeable; CI/all-required, E2E API Smoke, Handlers PG, and Canvas are green. Combined red was not used as the merge gate.

APPROVED on current head 35ed79dc3a. 5-axis review: Pause/Resume now fail closed with 409 when descendants exist unless ?cascade=true is explicit, preventing accidental subtree operations. Cascade=true preserves prior multi-workspace behavior; tests cover no-cascade 409 and cascade success for both pause and resume. No auth, gate, or merge-control changes; BP-required contexts are present+green.

APPROVE: verified current head, BP-required contexts present+green, mergeable=true. Cascade pause/resume is fail-closed by default: descendants block unless cascade=true is explicit; tests cover no-cascade 409 and cascade success. No gate/auth/merge-control weakening found.
