fix(tier2): deny %TEMP% writes - use app-data dir for temp files

Browse Source 
The Tier 2 agent wrote audit_exception_handling.py output to
C:\\Users\\Ed\\AppData\\Local\\Temp\\audit_initial.json via shell
redirection. This is OUTSIDE the sandbox allowlist (which is
C:\\projects\\manual_slop_tier2 + C:\\Users\\Ed\\AppData\\Local\\
manual_slop\\tier2 + C:\\Users\\Ed\\AppData\\Local\\manual_slop\\
tier2_failures). The OpenCode session-level guard fires the 'ask'
prompt for paths outside the project root, which has no answer in an
autonomous session, so ops halted mid-track.

Fix (3 layers):

1. opencode.json.fragment: add bash deny rule
   '*AppData\\Local\\Temp\\*': 'deny' to BOTH the top-level
   permission.bash (for default agents) and the tier2-autonomous
   agent's permission.bash. The agent physically cannot run shell
   commands that target the global Temp dir.

2. conductor/tier2/agents/tier2-autonomous.md: add 'Temp files'
   convention telling the agent to use
   C:\\Users\\Ed\\AppData\\Local\\manual_slop\\tier2\\ for scratch
   / audit-output / intermediate files, NOT %TEMP%.

3. conductor/tier2/commands/tier-2-auto-execute.md: same convention
   in the slash command so the agent sees it at slash-command time.

Tests (default-on):
- test_agent_denies_temp_writes: agent prompt has the Temp deny in
  frontmatter bash + the app-data dir note
- test_config_fragment_denies_temp_writes: both top-level and agent
  bash have the deny rule

All 16 tier 2 slash command tests pass.

Also: cleaned up the leaked audit_initial.json + audit.json +
audit_after*.json from %TEMP% (they were leftovers from a prior
run). Re-ran setup against the live clone; opencode.json's agent
bash and top-level bash both have the deny rule.

- **Line endings:** preserve existing (CRLF stays CRLF, LF stays LF)
- **Throw-away scripts:** write to `scripts/tier2/artifacts/<track-name>/`, NOT the base directory
- **Run-time expectation:** tracks are 1-4 hours. If context runs out, note progress to disk and continue.
- **Temp files** (added 2026-06-17): NEVER write to `C:\Users\Ed\AppData\Local\Temp\` or `%TEMP%`. Use `C:\Users\Ed\AppData\Local\manual_slop\tier2\` for scratch / audit-output / intermediate files. The bash deny `*AppData\Local\Temp\*` will block writes; the OpenCode session's outer guard will fire the "ask" prompt for reads — both halt autonomous ops.
