fix(signals): classify C# and Dart gRPC service stubs as generated

[jimcody1995]

Summary

Extend isGeneratedFile to recognize grpc-dotnet service stubs (*Grpc.cs) and Dart gRPC service stubs (.pbgrpc.dart), matching the existing Java *Grpc.java, Kotlin GrpcKt.kt, and Swift .grpc.swift conventions. Includes positive/negative isGeneratedFile / classifyChangedFile assertions and classification-table entries.

Fixes #2145

Scope

• Conventional Commit title format.
• Focused — path-matchers + unit tests only.
• Follows CONTRIBUTING.md.
• Linked open issue (feat(review): render changed-files summary as a collapsible table in the unified comment #2145 changed-files summary rendering depends on accurate classifyChangedFile).

Validation

• git diff --check
• npm run test:ci on Node 22
• npm audit --audit-level=moderate — 0 vulnerabilities
• Unit tests cover isGeneratedFile, classifyChangedFile, and the representative cases table

If any required check was skipped, explain why:

• None skipped.

Safety

• No secrets, auth, or UI changes.
• N/A for UI Evidence.

UI Evidence

N/A — signals-only change with no visible UI.

Notes

Incremental path-matcher parity supporting the changed-files summary pipeline (#2145). Does not deliver the collapsible renderer — only closes generated-classification gaps for C#/Dart gRPC stubs.

Conflict avoidance: Touches only src/signals/path-matchers.ts and test/unit/path-matchers.test.ts. Zero overlap with open PRs (#3718 finding severity floor, #3712 visual shot bounds, #3704 miner calibration types, #3702 miner README, #3698 ignored-author gate).

🛑 Suggested Action - Reject/Close

• AI reviewers agree on a likely critical defect: The PR claims 'Fixes feat(review): render changed-files summary as a collapsible table in the unified comment #2145' but feat(review): render changed-files summary as a collapsible table in the unified comment #2145's actual title/scope ('render changed-files summary as a collapsible table in the unified comment') is a UI rendering feature this diff does not implement — the linked issue is not genuinely closed or advanced by this path-matcher-only change, so the required issue-linkage justification is unsubstantiated. — Resolve the flagged defect, or override if the AI reviewers are mistaken, then re-run the gate.

Review summary
This diff extends isGeneratedFileFrom in src/signals/path-matchers.ts with two new regexes (grpc.cs and .pbgrpc.dart) to classify C# and Dart gRPC service stubs as generated, mirroring the existing Java/Kotlin/Swift conventions, and adds corresponding positive/negative unit tests plus classification-table entries. The regex logic itself is correct and consistent with the established pattern in this file. However, the PR claims to fix #2145, but the linked issue per its title ('render changed-files summary as a collapsible table in the unified comment') is about a UI rendering feature, not generated-file classification accuracy — this diff does not close or substantively advance that issue's actual scope, which is a real concern under this repo's issue-linkage requirement.

Blockers

• The PR claims 'Fixes feat(review): render changed-files summary as a collapsible table in the unified comment #2145' but feat(review): render changed-files summary as a collapsible table in the unified comment #2145's actual title/scope ('render changed-files summary as a collapsible table in the unified comment') is a UI rendering feature this diff does not implement — the linked issue is not genuinely closed or advanced by this path-matcher-only change, so the required issue-linkage justification is unsubstantiated.

Nits — 5 non-blocking

• src/signals/path-matchers.ts: the new `/grpc\.cs$/` regex (like the pre-existing `/grpc\.java$/` and `/grpckt\.kt$/`) has no word boundary before 'grpc', so it would also match a hand-written file merely ending in those letters (e.g. a file literally named `backgrpc.cs`); low real-world risk given the convention is already established, but worth a shared comment noting the tradeoff.
• test/unit/path-matchers.test.ts: the new C#/Dart test block is grouped separately from the existing Java gRPC test right below it — consider merging into one 'grpc service stubs across protoc plugins' test for readability, matching the file's existing terse style.
• Clarify or correct the issue link — either point to an issue that specifically covers generated-file classification gaps for C#/Dart gRPC stubs, or get maintainer sign-off that this incremental parity work is accepted as a partial step toward feat(review): render changed-files summary as a collapsible table in the unified comment #2145.
• Consider adding a boundary-anchored variant (e.g. requiring the preceding character not be an identifier character) for the bare `grpc.<ext>` suffix patterns across Java/Kotlin/C# in a follow-up, to reduce accidental matches on non-generated files.
• Readiness score is below the configured threshold — Use the readiness panel as advisory maintainer context; the score does not block this PR.
