feat(task): add cache fingerprint ignore patterns

[fengmk2]

Allow tasks to exclude specific files/directories from cache fingerprint
calculation using glob patterns with gitignore-style negation support.

This enables selective caching for tasks like package installation where
only dependency manifests (package.json) matter for cache validation,
not implementation files. Cache hits occur when ignored files change.

Key features:

• Optional fingerprintIgnores field accepts glob patterns
• Negation patterns (!) to include files within ignored directories
• Leverages existing vite_glob crate for pattern matching
• Fully backward compatible (defaults to None)

Example:

{"fingerprintIgnores": ["node_modules/**","!node_modules/**/package.json"]}

Note

Adds gitignore-style glob patterns to filter post-run fingerprint inputs, wiring config through execution and caching to control cache invalidation.

• Core fingerprinting:
  • PostRunFingerprint::create() filters path_reads via vite_glob::GlobPatternSet, honoring negation and order of fingerprint_ignores.
• Config/Fingerprint:
  • Add TaskConfig.fingerprint_ignores?: Option<Vec<Str>>.
  • Include fingerprint_ignores in CommandFingerprint to affect cache keys.
  • Propagate in ResolvedTaskConfig::resolve_command() and builtin resolver.
• Caching/Execution flow:
  • CommandCacheValue::create() and schedule.rs pass fingerprint_ignores to post-run fingerprint creation.
  • Bump task cache DB user_version to 3 and adjust migration handling.
• Tests/Fixtures:
  • Extensive unit tests for pattern filtering and cache-key sensitivity; add fixture and CLI snap-test demonstrating ignore/negation behavior.
• Docs:
  • Add RFC documenting schema, behavior, examples, and implementation details.

Pull Request Overview

This PR adds cache fingerprint ignore patterns to allow tasks to exclude specific files/directories from triggering cache invalidation. The feature enables selective caching where only certain files (like package.json) matter for cache validation, not all accessed files.

Key changes:

• Adds optional fingerprintIgnores field to task configuration supporting glob patterns with gitignore-style negation
• Leverages existing vite_glob crate for pattern matching with last-match-wins semantics
• Maintains full backward compatibility with no behavior changes when field is omitted
