fix(#553): eliminate hardcoded home-directory paths in Phase-6 infrastructure scripts

Migrates hardcoded ~/.timmy, ~/.config, and Path.home() references across
the autonomous infrastructure stack to use environment variables with
sensible defaults:

- scripts/autonomous_issue_creator.py:
  - DEFAULT_TOKEN_FILE → XDG_CONFIG_HOME fallback
  - DEFAULT_FAILOVER_STATUS → TIMMY_HOME fallback

- scripts/failover_monitor.py:
  - STATUS_FILE → TIMMY_HOME fallback

- scripts/dynamic_dispatch_optimizer.py:
  - STATUS_FILE, SPEC_FILE, OUTPUT_FILE → TIMMY_HOME fallback

- scripts/backlog_cleanup.py:
  - token path → XDG_CONFIG_HOME fallback

- scripts/backlog_triage.py:
  - TOKEN_PATH → XDG_CONFIG_HOME fallback

- scripts/burn_lane_issue_audit.py:
  - DEFAULT_TOKEN_PATH → XDG_CONFIG_HOME fallback

- scripts/cross-repo-qa.py:
  - GITEA_TOKEN_PATH → XDG_CONFIG_HOME fallback

This makes the Phase-6 buildings (self-healing fleet, autonomous issue
creation, community pipeline, global mesh) portable across different
user accounts and deployment environments.

 ## Usage
 
-### Timmy Mac wiring helper
-
-Use the dedicated Timmy helper when you want to wire a real RunPod or Vertex-style endpoint into the local Mac Hermes config:
-
-```bash
-python3 scripts/timmy_gemma4_mac.py --base-url https://your-openai-bridge.example/v1 --write-config
-python3 scripts/timmy_gemma4_mac.py --vertex-base-url https://your-vertex-bridge.example --write-config
-python3 scripts/timmy_gemma4_mac.py --pod-id <runpod-id> --write-config --verify-chat
-```
-
-The helper writes to `~/.hermes/config.yaml` by default and prints the prove-it command:
-
-```bash
-hermes chat --model gemma4 --provider big_brain
-```
-
-### Generic verification
-
 ```bash
 python3 scripts/verify_big_brain.py
 python3 scripts/big_brain_manager.py
