test: reduce and improve tests in fuzzy_schedule and dotnet

[github-actions]

Test Suite Reduction: src/fuzzy_schedule.rs + src/runtimes/dotnet/extension.rs

What was wrong

• test_cron_format (fuzzy_schedule.rs): only validated the minute (0–59) and hour (0–23) fields of the generated cron expression for a Daily schedule. The last three fields (day-of-month, month, day-of-week) were unchecked — a regression that added a day-of-week or day-of-month constraint would silently convert a daily schedule into a weekly or monthly one without any test failure.

• test_generate_schedule_yaml (fuzzy_schedule.rs): always: true was not asserted. That flag is load-bearing: without it, ADO only fires the schedule when the target branch has new commits since the last run. Removing it from the template would cause pipelines to silently skip unconditional runs, and the old test would not catch it.

• test_generate_schedule_yaml_with_branches (fuzzy_schedule.rs): same missing always: true assertion as above.

• test_validate_global_json_sentinel_skips_injection_check (dotnet/extension.rs): the sole assertion was is_ok(). Since global.json contains no injection characters ($(, ${{, $[, ##vso[, {{, or newlines), validate() returns Ok regardless of whether the sentinel bypass exists. The test would pass even if the sentinel recognition code was deleted. This is a strict subset of the stronger test_validate_global_json_sentinel_accepted_with_file_present, which exercises the meaningful scenario (compile directory contains a global.json file and the sentinel version resolves the conflict).

Changes

Test	File	Action	Reason
test_cron_format	fuzzy_schedule.rs	Rewritten	Added assert_eq!(parts[2], "*"), assert_eq!(parts[3], "*"), assert_eq!(parts[4], "*")
test_generate_schedule_yaml	fuzzy_schedule.rs	Rewritten	Added assert!(yaml.contains("always: true"))
test_generate_schedule_yaml_with_branches	fuzzy_schedule.rs	Rewritten	Added assert!(yaml.contains("always: true"))
test_validate_global_json_sentinel_skips_injection_check	dotnet/extension.rs	Removed	Vacuous — is_ok() always true; strict subset of test_validate_global_json_sentinel_accepted_with_file_present

Verification

• cargo test: all 1 761 + integration tests pass ✅
• cargo clippy --all-targets --all-features: no warnings ✅
