Evidence-Ticket: OMN-9743

Summary

Implements HookActivationResolver in omnibase_infra/hooks/ — Track 1 Task 4 of the omniclaude restructure plan (parent epic OMN-9737).

• Creates src/omnibase_infra/hooks/hook_activation_resolver.py — resolves a list[ModelHookActivation] from omnibase_core into a composite bitmask, setting bits only for enabled_by_default=True activations
• Lenient rollout-safety policy: unresolvable activations log a warning and are skipped (never crash the runtime)
• Ships 4 unit tests: mixed enabled/disabled, empty list, all enabled, all disabled

Context

Depends on ModelHookActivation (omnibase_core, already present) and ModelPackageHookActivations (omnibase_core PR: feat(OMN-9743): add ModelPackageHookActivations). This resolver is the compositing engine that turns per-package hook_activations.yaml declarations into the ONEX_HOOKS_MASK bitmask used by EnumHookBit.hook_enabled().

The broad Exception catch uses # noqa: BLE001 per plan spec: lenient rollout-safety policy means partial mask (skipping bad entries) is safer than crashing runtime on malformed activation declarations.

Test plan

• uv run pytest tests/unit/hooks/test_hook_activation_resolver.py -v — 4 passed
• uv run mypy src/omnibase_infra/hooks/hook_activation_resolver.py --strict — no issues
• pre-commit run --all-files — all hooks passed
• HookActivationResolver([ModelHookActivation(hook_bit=CI_REMINDER, enabled_by_default=True)]).compute_mask() returns mask with CI_REMINDER bit set
• enabled_by_default=False activations do NOT set bits
• Empty activations list returns 0
