fix(ci): use GITHUB_EVENT_BEFORE env var in detect-changes push job

mc#917 root fix.

Gitea Actions does not expose github.event.before as a ${{ }} template
expression that resolves in shell scripts for push events — it silently
becomes an empty string. This caused `git cat-file -e ""` to hang
indefinitely on some runner configurations (10m timeout was masking the
failure via continue-on-error: true).

Fix: use GITHUB_EVENT_BEFORE env var (set by the runner for push
events) instead of the broken template expression. Also guard both
`git cat-file -e` calls with `timeout 30` to prevent future hangs if
BASE is ever malformed.

-"""OFFSEC-003 regression backstop — sanitize_a2a_result invariant across all A2A tool exit points.
-
-Scope
------
-Every public callable in ``a2a_tools_delegation`` that returns peer-sourced content
-must pass its output through ``sanitize_a2a_result`` before returning to the agent
-context.  These tests inject boundary markers and control sequences from a
-mock-peer response and assert the returned value is the sanitized form.
-
-Test coverage for:
-  - ``tool_delegate_task``            — main sync path
-  - ``tool_delegate_task``            — queued-mode fallback path
-  - ``_delegate_sync_via_polling``    — internal polling helper
-  - ``tool_check_task_status``        — filtered delegation_id lookup
-  - ``tool_check_task_status``        — list of recent delegations
-
-Issue references: #491 (delegate_task), #537 (builtin_tools/a2a_tools.py sibling)
-
-Key sanitization facts (for test authors):
-  • _escape_boundary_markers: inserts ZWSP (U+200B) before '[' at line-start.
-    The substring "[A2A_RESULT_FROM_PEER]" IS STILL in the output (preceded by ZWSP).
-    Assertion pattern: assert ZWSP in result.
-  • _strip_closed_blocks: removes everything after the closer.
-    Assertion pattern: assert "hidden content" not in result.
-  • Error path: when peer returns an error-prefixed string (starts with
-    _A2A_ERROR_PREFIX), the raw error text is included in the user-facing
-    "DELEGATION FAILED" message. This is intentional — errors from peers
-    are surfaced as errors, not as sanitized results.
