[luv-33] Default Claude to Opus 5

[NiveditJain]

Switches the built-in Claude model default from claude-opus-4-8 to claude-opus-5.

Changes

• luv/__init__.py — model fallback in both launch() and resume(), plus the -m help text
• README.md — "How it works" step 4 and the -m MODEL flag row
• tests/test_agents.py — default-model assertion

The -m MODEL flag still overrides the default, and Codex still uses its own CLI default.

Testing

python3 -m unittest discover -s tests — 5 tests, all pass.

[PASS] Approved

Straightforward model-default bump: claude-opus-4-8 -> claude-opus-5 in three locations (launch, resume, help text) plus test assertion and README. No logic changes — just a string swap.

What is good:

• All 5 tests pass
• No debug leftovers, no secret leaks
• README and help text kept in sync with code
• -m MODEL override path unchanged (user can still pin a specific model)
