fix(ci): increase Go test timeouts for cold runner performance

Cold runners with -race flag need 13-25 minutes for the full ./... suite
(compilation + race-instrumented execution), exceeding the previous:
- 60s diagnostic per-package timeout  -> 300s (handlers, pendinguploads)
- 10m main suite timeout             -> 30m
- 15m job-level ceiling               -> 35m

The OOM issue (mc#1099) was fixed by the 10m timeout, but that was
calibrated for warm cache (~5-7m). Cold runners hit 13-25m, causing
the suite to be killed mid-execution with non-zero exit, blocking all
staging PRs.

All 36 Go packages pass locally (non-race, ~20s total). No test changes
— only CI timeout calibration.

+# E2E test: workspace broadcast and talk-to-user platform abilities.
+#
+# What this proves:
+#   1. talk_to_user_enabled (default true) — POST /notify works out-of-the-box.
+#   2. PATCH /workspaces/:id/abilities { talk_to_user_enabled: false } disables
+#      delivery: /notify → 403 with error="talk_to_user_disabled" + delegate hint.
+#   3. Re-enabling talk_to_user_enabled restores delivery.
+#   4. broadcast_enabled (default false) — POST /broadcast → 403 when disabled.
+#   5. PATCH { broadcast_enabled: true } enables fan-out.
+#   6. POST /broadcast delivers to all non-sender, non-removed workspaces:
+#      - Returns {"status":"sent","delivered":N}
+#      - Receiver's activity log has a broadcast_receive entry with the message.
+#      - Sender's activity log has a broadcast_sent entry.
+#   7. The sender itself does NOT receive a broadcast_receive entry.

 ### get_workspace_info
 Use to introspect your own identity (e.g. before reporting back to the user, or to determine whether you're a tier-0 root that can write GLOBAL memory).
 
+### broadcast_message
+Use for urgent, org-wide signals: critical status changes, emergency stop instructions, coordinated task announcements. Every non-removed workspace receives the message in its activity log (poll-mode agents see it on their next poll; push-mode canvases get a real-time banner).

 ### send_message_to_user
 Use proactively across the lifecycle of a task — early to acknowledge, mid-flight to update, late to deliver. Never paste file URLs in the message body — always pass absolute paths in `attachments` so the platform serves them as download chips (works on SaaS where external file hosts are unreachable).
