feat(training): merge Evennia & Tower patterns to reach 5K code pairs (closes #573)

Add scripts/merge_code_patterns_573.py — merges Evennia/Tower patterns
from training-data/code-patterns-evennia-&-tower.jsonl into the user's
~/.hermes/training-data/code-patterns.jsonl, bringing total to 5000 pairs.

Also add training-data/README-5K.md documenting the 5K completion.

The merge renumbers IDs to avoid collisions.

After merge, ~/.hermes/training-data/code-patterns.jsonl contains:
tool-usage: 1000, gitea-api: 1000, hermes-agent: 1000, deployment: 600,
evennia-support: 400, + subdomains from Evennia/Tower: 1000 = 5000 total.

Training Factory #573 complete.
