Proposed Changes

• Exclude IngestTimeParsers/ YAML from the legacy query-time parser template validator's changed-file selection.
• Keep ingestion-time validation on its dedicated workflow and preserve trusted-master script loading in the privileged workflow.
• Add regression coverage for mixed QTP/ITP changes, ITP-only changes, and existing QTP behavior; document the validator boundary.
• Validation: the documented offline ASIM ingestion-time unittest suite passed (169 tests).

What changed in this PR

This PR separates legacy query-time parser template validation from ingestion-time parser validation, addressing the incorrect routing encountered in #15463.

Changes:

• Excludes IngestTimeParsers/ YAML files from legacy validation while preserving existing query-time YAML selection.
• Adds regression tests for mixed changes, ingestion-time-only changes, and existing query-time behavior.
• Documents the boundary between the legacy validator and the dedicated ingestion-time workflow.

File	Description
.script/​tests/​asimParsersTest/​VerifyASimParserTemplate.py	Uses the shared query-time file filter and clarifies validator scope.
.script/​tests/​asimParsersTest/​ingestTimeParser/​tests/​test_asim_parser_template_routing.py	Adds regression coverage for parser file selection.
.script/​tests/​asimParsersTest/​ingestTimeParser/​README.md	Documents the separate validation paths.
.script/​tests/​asimParsersTest/​asim_parser_file_utils.py	Adds the ingestion-time directory exclusion, supporting both path separators.
