feat(FN-5405): remove broad-scope triage heuristics and UI advisory chips/b

Removes the broad-scope detection feature end-to-end: the TaskCard chip and TaskDetailModal advisory banner are gone from the dashboard, the triage heuristic that flagged tasks as broad-scope has been deleted from the engine along with its associated run-audit events, and documentation references ha

@@ -55,7 +55,6 @@ Features:
- PR/issue badges with live updates
- GitHub provenance marker on task cards imported from GitHub (`sourceType: github_import`), shown alongside existing footer metadata like timers
- Agent-created provenance badge in task card headers for agent-originated tasks (`sourceType: agent_heartbeat` or `sourceType: automation`, or legacy tasks with `sourceAgentId`), with labels preferring `sourceMetadata.agentName` over raw agent IDs
- Broad-scope advisory surfacing from `task.sourceMetadata.broadScopeFlag`: TaskCard shows a warning-tinted `Broad scope` chip with score/reasons tooltip, and TaskDetailModal shows a read-only `Triage broad-scope advisory` banner with score, humanized reasons, and signal summary. This is informational only and does not alter lifecycle, scheduling, pause state, or merge behavior.
- Column ordering semantics: `todo` mirrors scheduler pickup order (priority descending, then oldest `createdAt`, then task ID); `triage`, `in-progress`, `in-review`, and `archived` remain priority-first with task-ID tie-breaks; `done` is ordered by most recent completion first (`columnMovedAt`, then `updatedAt`, then `createdAt` fallback)

## Broad-scope triage intake (`[triage]`)
- Trigger shape: `TriageProcessor.finalizeApprovedTask()` scores the prompt/description against `packages/engine/src/triage-broad-scope-heuristics.ts` and flags advisory decomposition risk when the score reaches `>= 3`.
- Diagnostic: `[triage] <taskId>: broad-scope flag at triage — score=<n>, reasons=<csv>`.
- Fail-soft diagnostic: `[triage] <taskId>: broad-scope heuristic failed open: <message>` when the helper throws; the task still proceeds to `todo`.
- Audit event: `task:broad-scope-flagged-at-triage` with `{ score, reasons, signals, thresholds, version }`.
- Task log side effect: `Broad-scope triage flag` advising operators to decompose via `fn_task_create` or set `breakIntoSubtasks=true` before execution.
## Resume instrumentation (FN-5389, Phase 1)
Dashboard Phase 1 resume instrumentation adds observation-only client/server traces for refetch/reconnect attribution. It does not change visibility/pageshow/SSE behavior; FN-5392 consumes this data for fixes.

- Only keep a task as one unit if it genuinely has 5 or fewer focused steps with a clear scope
- If you decide not to split an M/L task, proceed with a normal PROMPT.md specification
**Broad-scope decomposition signals:**
- Size L tasks, especially when the planned step count would reach 9 or more.
- Plans whose implementation-step count would reach 12 or more (additive signal — counts even when the surrounding "more than 7/10 steps" threshold above has not yet fired).
- Tasks whose declared \`## File Scope\` would list 20 or more entries.
- Descriptions that quantify large remediation batches (for example "47 failing tests", "30+ broken files") at or above 30 items — treat as a strong signal that the work should be partitioned by subsystem or file group before specifying.
- When two or more of the signals above fire together, default to splitting via \`fn_task_create\`. If you still choose to keep the task as a single unit, justify the decision explicitly in the PROMPT.md \`## Mission\` paragraph.
## Triage tools
You have these extra tools during triage:
- \`fn_task_list\` — list existing active tasks

- Coordination overhead (worktrees, dependency wiring, merge sequencing) is real — only split when the parallelism or scope-clarity benefit clearly outweighs it
- If you decide not to split an M/L task, proceed with a normal PROMPT.md specification
**Broad-scope decomposition signals:**
- Size L tasks, especially when the planned step count would reach 9 or more.
- Plans whose implementation-step count would reach 12 or more (additive signal — counts even when the surrounding "more than 7/10 steps" threshold above has not yet fired).
- Tasks whose declared \`## File Scope\` would list 20 or more entries.
- Descriptions that quantify large remediation batches (for example "47 failing tests", "30+ broken files") at or above 30 items — treat as a strong signal that the work should be partitioned by subsystem or file group before specifying.
- When two or more of the signals above fire together, default to splitting via \`fn_task_create\`. If you still choose to keep the task as a single unit, justify the decision explicitly in the PROMPT.md \`## Mission\` paragraph.
## Triage tools
You have these extra tools during triage:
