fix: code health cleanup and test gaps (#921, #860)

[microsasa]

Summary

Addresses #921 (code hygiene) and #860 (render_detail test gaps).

Changes

#921 — Code hygiene (3 findings):

• Remove dead # Typed event helpers section header in models.py (content was moved elsewhere)
• Convert mypy-style # type: ignore[arg-type] to # pyright: ignore[reportArgumentType] with correct rule names (cli.py:290, logging_config.py:56)
• Remove unnecessary # type: ignore[import-untyped] on watchdog import — pyright doesn't flag it (watchdog ships py.typed)
• Replace getattr/hasattr with vars() in test_packaging.py for module-level checks, per "no runtime type interrogation" rule
• Intentionally keep hasattr for SessionEvent.parse_data regression guard — needs full MRO traversal to catch inherited methods on Pydantic models

#860 — render_detail test gaps:

• Gap 1 (shutdownType=None): Already covered — shutdownType is str (not Optional), defaults to "", and Pydantic rejects None. Existing tests at lines 2971 and 2984 cover the falsy branch.
• Gap 2 (TOOL_EXECUTION_COMPLETE with model field): Added test_tool_execution_with_model_field — exercises the if data.model: branch
• Added test_tool_execution_with_empty_model_string — documents falsy model="" edge case behaviour

Review notes

• Triple adversarial review by Codex, Opus 4.6, and Sonnet 4.6
• Opus/Sonnet both caught the vars(SessionEvent) MRO weakness — fixed by restoring hasattr for that specific assertion
• Sonnet caught the model="" edge case gap — test added
• make check passes: lint ✅ pyright ✅ bandit ✅ tests 99% ✅ e2e 86 ✅

Also recommending closure of stale issues

• [aw][test audit] _detect_resume: missing regression test for ASSISTANT_TURN_START-only post-shutdown not marking session as [Content truncated due to length] #761: _detect_resume was deleted in PR perf(parser): single-pass resume detection in _first_pass (#955) #990; the scenario is covered by TestOrphanedTurnStartDoesNotInflateActiveCalls
• [aw][test audit] _full_scandir_discovery is_dir() OSError guard is untested #846: Already fixed — test_is_dir_oserror_entry_is_skipped added in commit 5f456e7

Closes #921
Closes #860

Pull request overview

This PR addresses two maintenance efforts in copilot_usage: (1) code hygiene cleanups (type-ignore style consistency, removing dead comments, avoiding getattr/hasattr in packaging tests), and (2) closing test coverage gaps for render_detail._build_event_details().

Changes:

• Standardize type-check suppression comments to # pyright: ignore[...] and remove an unnecessary watchdog import suppression.
• Update packaging/public-API tests to use vars() lookups instead of getattr/hasattr (with an intentional exception for a full-MRO regression guard).
• Add tests covering TOOL_EXECUTION_COMPLETE detail rendering when model is present or an empty string.
