fix(web): terminal links drop a trailing colon

[ValeraZSD]

Compiler errors end their location with a colon: ./main.go:10:5: undefined: x, /src/main.c:10:5: error: .... For paths starting with ./, /, ~/ or a drive letter, the terminal link kept that colon, so the :line:col suffix stopped parsing and Ctrl/Cmd-click opened a file literally named main.c:10:5:.

The fix adds : to the trailing punctuation trimmed from terminal links. Tests cover Go and gcc output (POSIX and Windows paths), a bare trailing colon, and that line and column still reach resolvePathLinkTarget.

Summary by CodeRabbit

• Bug Fixes
  • Improved terminal link handling for compiler diagnostics by excluding trailing colons from file paths while preserving line and column details.
  • Preserved trailing colons on URL links.

🟡 Medium src/terminal-links.ts:37

URL matches ending with a legitimate colon are emitted without that colon, so https://example.test/api/items/foo: becomes https://example.test/api/items/foo and Ctrl/Cmd-click targets a different resource. Because TRAILING_PUNCTUATION_PATTERN is shared by URL and path processing, adding : here strips it from both; apply colon trimming only to path diagnostics or use separate URL and path trimming rules.

Approvability

Verdict: Would Approve

Macroscope's review found this PR approvable — This is a narrowly scoped terminal-link bug fix with focused tests and no product-default, infrastructure, security, or static-analysis configuration changes. The shared punctuation rule also affects URLs ending in a legitimate colon; that unresolved Medium finding is a separate repository approval blocker.

Not approved because:

Fair point. The colon is now trimmed from paths only, and URLs keep the old punctuation rule. Added a test for a URL that ends in a colon.

📝 Walkthrough

Walkthrough

Terminal link extraction now trims trailing colons from path links while preserving trailing colons on URL links. Tests cover compiler diagnostic path extraction and line-column resolution.

Changes

Compiler diagnostic path links

Layer / File(s)	Summary
Trim and test diagnostic paths apps/web/src/terminal-links.ts, apps/web/src/terminal-links.test.ts	Path links use a punctuation pattern that includes colons; URL links retain their existing punctuation handling. Tests cover URL and path extraction, including diagnostic locations with line and column numbers.
