feat(validator): per-file rule exclusions via fileExcludes

[mrwogu]

Summary

• New fileExcludes config option allows disabling specific validation rules for files matching glob patterns
• Uses picomatch for glob matching
• Wired through promptscript.yaml -> compiler -> validator pipeline

Example

validation:
  fileExcludes:
    - pattern: "skills/**/SKILL.md"
      rules: [PS011]
    - pattern: "vendor/**"
      rules: [empty-block, PS012]

Changes

• ValidatorConfig.fileExcludes (validator types)
• PromptScriptConfig.validation.fileExcludes (core config types)
• Validator.validate() computes per-file excluded rules before the rule loop
• JSON schema updated (schema/config.json)
• Docs: config.md reference + security.md guidance on false positives
• 5 new tests covering match/no-match/multiple entries/empty config

Test plan

• 394 validator tests pass (5 new)
• Full pipeline: format, lint, typecheck, test, validate, schema:check, skill:check, docs:formatters:check
• CI green
