test: reduce and improve tests in src/compile/types.rs

[github-actions]

Test Suite Reduction: src/compile/types.rs

What was wrong

• test_cache_memory_bool_false: only asserted !cm.is_enabled(), missing the cm.allowed_extensions().is_empty() assertion that the symmetrical test_cache_memory_bool_true includes. The Enabled(false) variant's allowed_extensions() code path was untested.

• test_pr_trigger_config_empty_filters: a test named "empty_filters" that claimed to verify a filters: {} block produces all-None fields — but only checked 3 of the 13 nullable fields on PrFilters (title, author, draft). Ten fields were silently skipped: source_branch, target_branch, commit_message, labels, changed_files, time_window, min_changes, max_changes, build_reason, expression.

• test_pr_trigger_config_mode_explicit_synthetic: its only assertion (assert_eq!(mode, PrMode::Synthetic)) is identical to test_pr_trigger_config_mode_default_synthetic. The existing mode-trio (default_synthetic + explicit_policy + invalid_value_errors) fully documents the mode: field — the explicit-default variant adds no regression protection that the other three tests don't already provide.

Changes

Test	Action	Reason
test_cache_memory_bool_false	Rewritten	Vacuous — missing allowed_extensions().is_empty() assertion; asymmetric with bool_true
test_pr_trigger_config_empty_filters	Rewritten	Incomplete — extended to cover all 13 nullable PrFilters fields
test_pr_trigger_config_mode_explicit_synthetic	Removed	Redundant — assertion is strict subset of test_pr_trigger_config_mode_default_synthetic

Verification

• cargo test: 1820 tests pass ✅ (was 1821 — one redundant test removed)
• cargo clippy --all-targets --all-features: no errors or warnings ✅
