fix(gha): exclude secrets test package from secret-scan workflow

patterns_test.go contains credential-shaped fixture strings
(e.g. ghp_EXAMPLE1111...) as intentional test inputs to verify
the regex patterns. These are representative shape strings, not real
credentials. Adding the file to the SELF exclusion list keeps the
scan focused on genuine leaks while allowing the test suite to
exercise the full pattern set.

This unblocks PR #1272 (secrets package coverage fix) which adds
two additional test cases (TestCompileError, TestScanBytes_CompileErr)
to the same test file.

-# Architecture:
-#   1. Ephemeral Postgres + Redis (docker, unique container names)
-#   2. workspace-server built from source, started with
-#      MOLECULE_ENV=development (fail-open auth)
-#   3. canvas dev server (npm run dev) on :3000
-#   4. Playwright tests create workspaces via API, point them at an
-#      in-process echo runtime, and exercise the full send/receive
-#      round-trip through the browser.
-#
-# Parallel-safety: same pattern as e2e-api.yml — per-run container names
-# and ephemeral host ports so concurrent jobs on the host-network runner
-# don't collide.

- *  - openclaw → `/agent-home` (the agent's identity/state — the

- *    `~/.openclaw/` inside the container, which `/agent-home` maps to
- *    via the Phase 2b docker-exec backend).
- *  - everything else (claude-code, hermes, external-like, undefined)
- *    → `/configs` (the legacy default — managed config that flows
- *    through the per-runtime indirection in
- *    workspace-server/internal/handlers/template_files_eic.go).
- *
- *  When the runtime is undefined (legacy callers that don't thread
- *  `data` through, or a workspace whose runtime field hasn't loaded
- *  yet) the default is `/configs` — matches today's behaviour, no
- *  surprise.
- *
- *  Note on `/agent-home` pre-Phase-2b: the backend short-circuits
- *  with HTTP 501 and the canonical "implementation pending" body.
- *  The tab renders empty + the error banner explains. This is by
- *  design — lets us land the canvas UX before the backend ships,
- *  per the RFC's phased rollout. The 501 is graceful: it doesn't
- *  poison error toasts or generate "workspace not found" noise.

- * 3. usePalette(true) without provider → MOL_DARK
- * 4. accent=null returns base palette unchanged

-# 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.
-#
-# Usage:  tests/e2e/test_workspace_abilities_e2e.sh
-# Prereqs: workspace-server on http://localhost:8080, MOLECULE_ENV != production
