build(deps): bump regex from 1.11.2 to 1.12.2

[dependabot]

Bumps regex from 1.11.2 to 1.12.2.

Changelog

Sourced from regex's changelog.

1.12.2 (2025-10-13)

This release fixes a cargo doc breakage on nightly when --cfg docsrs is enabled. This caused documentation to fail to build on docs.rs.

Bug fixes:

• [BUG #1305](rust-lang/regex#1305): Switches the doc_auto_cfg feature to doc_cfg on nightly for docs.rs builds.

1.12.1 (2025-10-10)

This release makes a bug fix in the new regex::Captures::get_match API introduced in 1.12.0. There was an oversight with the lifetime parameter for the Match returned. This is technically a breaking change, but given that it was caught almost immediately and I've yanked the 1.12.0 release, I think this is fine.

1.12.0 (2025-10-10)

This release contains a smattering of bug fixes, a fix for excessive memory consumption in some cases and a new regex::Captures::get_match API.

Improvements:

• [FEATURE #1146](rust-lang/regex#1146): Add Capture::get_match for returning the overall match without unwrap().

Bug fixes:

• [BUG #1083](rust-lang/regex#1083): Fixes a panic in the lazy DFA (can only occur for especially large regexes).
• [BUG #1116](rust-lang/regex#1116): Fixes a memory usage regression for large regexes (introduced in regex 1.9).
• [BUG #1195](rust-lang/regex#1195): Fix universal start states in sparse DFA.
• [BUG #1295](rust-lang/regex#1295): Fixes a panic when deserializing a corrupted dense DFA.
• BUG 8f5d9479: Make regex_automata::meta::Regex::find consistently return None when WhichCaptures::None is used.

1.11.3 (2025-09-25)

This is a small patch release with an improvement in memory usage in some cases.

Greptile Overview

Summary

This PR updates the regex crate from 1.11.2 to 1.12.2, along with its sub-dependency regex-automata from 0.4.10 to 0.4.13.

Key improvements in this update:

• Fixed memory usage regression for large regexes (introduced in regex 1.9)
• Fixed panic in lazy DFA for especially large regexes
• Fixed universal start states in sparse DFA
• Fixed panic when deserializing corrupted dense DFA
• Fixed cargo doc breakage on nightly with --cfg docsrs

The codebase uses regex in three locations (priority.rs, pipeline.rs, parallel.rs) for pattern matching in priority rules. All usages follow safe patterns with Regex::new() wrapped in error handling (if let Ok(...)), making this update safe.

Confidence Score: 5/5

• This PR is safe to merge with no risk
• This is a standard dependency update from Dependabot that includes only bug fixes and performance improvements. The update addresses memory usage issues and prevents panics in edge cases. The codebase uses regex safely with proper error handling around all Regex::new() calls. No breaking API changes were introduced in this minor version bump.
• No files require special attention
