fix(handlers): add $6 placeholder for 'pending' in insertMCPDelegationRow

The INSERT has 8 column names but the VALUES clause only had 5
positional placeholders ($1-$5). The 'pending' status was passed as a
raw string literal instead of a placeholder, and pq's internal arg
count then misaligned all subsequent args.

Before (broken): VALUES ($1...$5, 'pending') with 6 args → pq error
After:           VALUES ($1...$6)   with 6 args → correct

Also adds sqlmock coverage for insertMCPDelegationRow (success + DB
error) and updateMCPDelegationStatus (success + error detail + DB
error logged-not-returned), bringing both from 0% to 100% coverage.

+// Regression coverage for the POLL-mode arm of the canvas user-message
+// data-loss bug (internal#470 sibling — tracked on internal#471).
+//
+// Bug (reported 2026-05-16 by CTO Hongming): "in canvas i sometimes lose
+// my own message when i exit chat". The push-mode arm was fixed by
+// #1347 (persistUserMessageAtIngest — a SYNCHRONOUS, before-dispatch,
+// context.WithoutCancel INSERT). #1347's framing asserted "poll-mode
+// workspaces were never affected — logA2AReceiveQueued already persists
+// at ingest". That assertion is OVERSTATED.
+//
+// Hongming's tenant (slug `hongming`, org 2c940477-...) has 4 workspaces,
+// ALL runtime=external with empty URL → ALL delivery_mode=poll (proven
+// empirically: a benign A2A probe returns the synthetic
+// {"delivery_mode":"poll","status":"queued"} envelope for every one).
+// So his reported loss is the POLL path, NOT the push path #1347 fixes.
+//
+// Root cause (poll arm): the poll-mode short-circuit (a2a_proxy.go ~402)
+// calls logA2AReceiveQueued and then IMMEDIATELY returns the synthetic
+// 200 {status:"queued"} to the canvas. But logA2AReceiveQueued's durable
+// INSERT runs inside h.goAsync(...) — a DETACHED goroutine with NO
+// happens-before barrier against the HTTP response. The canvas sees 200
+// ("message accepted") while the activity_logs row may not yet be — and,
+// on a workspace-server restart / deploy / OOM / EC2 hibernation between
+// the 200 and the goroutine's commit, NEVER will be — durable. There is
+// also no fallback (unlike push-mode's legacy-INSERT fallback): a
+// swallowed LogActivity error loses the message with only a log line.
+// Chat-history reads activity_logs (postgres_store.go:165-187); a missing
+// row = message gone on reopen. That is exactly Hongming's symptom.
+//
+// Fix (parity with push-mode): the poll-mode ingest persist of the
+// canvas user message must be SYNCHRONOUS — committed before the queued
+// 200 is returned — on a context.WithoutCancel derived context, so a
+// client disconnect on chat-exit and a post-response restart cannot lose
+// it. Behavior is never worse than today (best-effort; a persist error
+// still returns queued).
+//
+// TEST DESIGN NOTE: sqlmock.ExpectationsWereMet() hangs indefinitely if
+// the expected query never fires. We use a select+default+time.After
+// pattern so the test FAILS fast (not hangs) when the production code
+// regresses to async (the INSERT never fires before handler returns),
+// while still returning promptly when all expectations are met. The
+// insertDelay is kept small (50ms) to minimise suite-level timing
+// impact under -race detection, where mock delays are amplified by
+// the instrumenter's goroutine overhead.

-    to its display name (e.g. "mac laptop"). The agent sees its own
-    delegation-failure echoed back as if a peer delegated to it.
+    Internal #469: when a workspace delegates to a target that never picks
+    up the task, ``tool_delegate_task`` calls ``report_activity`` which
+    POSTs to the platform with source_id set to the *sender's* workspace
+    UUID (mandated by spoof-defense in workspace-server's a2a_proxy). The
+    activity API exposes that row under type=a2a_receive, so the inbox
+    poller re-fetches it. Without this guard the row is surfaced as
+    kind='peer_agent' with the workspace's own identity as peer_id —
+    the workspace sees its own delegation-failure echoed back as if a
+    peer had delegated to it.
 
-    A genuine inbound peer message ALWAYS has ``source_id`` set to a
-    DIFFERENT workspace than the one being polled — self-delegation is
-    already rejected upstream by two independent guards (the platform's
-    DelegationHandler.Delegate and the agent-side tool_delegate_task).
-    So ``source_id == workspace_id`` on the a2a_receive feed only ever
-    means a self-originated bookkeeping row, never a real peer.
+    The guard mirrors the existing _is_self_notify_row pattern: both
+    skip rows that would otherwise create spurious inbound signal. The
+    long-term fix (making the platform write a distinct activity_type
+    for agent-outbound rows) is tracked separately; this guard stays
+    because it only excludes rows the agent never wants.
 
-    Exception: ``method='delegate_result'`` rows ARE legitimately written
-    to the caller's own inbox with ``source_id == workspace_id`` — that
-    is the RFC #2829 PR-2 delegation-result delivery path
-    (handlers/delegation.go:pushDelegationResultToInbox). Those must keep
-    flowing to the agent, so they are explicitly NOT treated as echo.
+    ``workspace_id`` must be non-empty — an empty-string workspace_id
+    (single-workspace legacy path) can never match a UUID source_id, so
+    the predicate is always False there, which is safe.
 
-    Matched on (source_id == workspace_id) AND (method != 'delegate_result')
-    together so the RFC #2829 result-push is preserved while the
-    report_activity self-echo is filtered.
+    RFC #2829 PR-2 note: rows with method="delegate_result" are excluded
+    from the self-echo guard even when source_id matches our workspace_id.
+    The platform may write a delegation-result row with source_id set to
+    our workspace_id (e.g. a self-delegation or edge case in the platform's
+    result-writing path). Such rows must reach the inbox so that
+    message_from_activity can surface them as peer_agent inbound and the
+    runtime receives the delegation result. Silently filtering them as
+    self-echo would break delegation result delivery.

-# sets peer_id=source_id (non-empty) → kind=peer_agent, registry-resolved

-# delegation-result pushes (method='delegate_result'), which must keep
-# flowing. These tests pin both halves so a refactor that drops either
