fix(signals): classify WASM source maps as generated

[jimcody1995]

Summary

Extend isGeneratedFile source-map parity so bundler output like dist/pkg.wasm.map is classified as generated, matching existing JS/TS and front-end .map handling. Includes direct classifyChangedFile assertions for the hot-path category behavior.

Fixes #561

Scope

• The PR title follows type(scope): short summary Conventional Commit format, for example fix(api): restore profile access checks.
• This PR is focused and does not mix unrelated backend, UI, MCP, docs, dependency, and deploy changes.
• This follows CONTRIBUTING.md and does not reintroduce GitHub Pages, VitePress, site/, or CNAME.
• I linked an issue, or this is small enough that the summary explains why an issue is not needed.

Validation

• git diff --check
• npm run actionlint
• npm run typecheck
• npm run test:coverage locally; codecov/patch requires ≥99% coverage of the lines AND branches you changed (aim for 100% on your diff so CI variance does not fail near the threshold). Global coverage is a non-blocking trend with a loose 90% backstop, not the gate.
• npm run test:workers
• npm run build:mcp
• npm run test:mcp-pack
• npm run ui:openapi:check
• npm run ui:lint
• npm run ui:typecheck
• npm run ui:build
• npm audit --audit-level=moderate
• New or changed behavior has unit/integration tests for new branches, fallback paths, and sanitizer boundaries

If any required check was skipped, explain why:

• None skipped.

Safety

• No secrets, wallet details, hotkeys, coldkeys, user PATs, private keys, raw trust scores, private rankings, or private maintainer evidence are exposed.
• Public GitHub text stays sanitized, low-noise, and does not imply compensation guarantees or optimization tactics.
• Auth, cookie, CORS, GitHub App, Cloudflare, or session changes include negative-path tests.
• API/OpenAPI/MCP behavior is updated and tested where needed.
• UI changes use live API data or real empty/error/loading states, not production mock/demo fallbacks.
• Visible UI changes include a UI Evidence section below with JPG/JPEG or PNG screenshots arranged as organized, captioned, clickable thumbnails. SVG screenshots are not used as review evidence. Review-only screenshots or recordings are not committed to the repository.
• Public docs/changelogs are updated where needed; changelogs are only edited for release-prep PRs.

UI Evidence

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

Notes

Incremental maintenance parity for the path-matcher slop signals from #561. Supports generated-file classification work tracked in #2279.

⏸️ Suggested Action - Manual Review

Review summary
This change correctly extends the generated-file source-map matcher so `*.wasm.map` follows the same path as existing JS/TS/framework/style source maps, and the classifier hot path is covered directly. The implementation is narrowly scoped, preserves the existing normalization and category precedence, and the added tests exercise both `isGeneratedFile` and `classifyChangedFile` for the new extension. I do not see a reachable correctness issue in the visible diff.

Nits — 1 non-blocking

• src/signals/path-matchers.ts:78: If you expect more binary artifact source maps to follow, consider extracting the source-map extension list into a named constant so future additions do not keep lengthening the regex inline.

Signal definitions

• Related work = same linked issue, overlapping active PRs, or title/path similarity.
• Change scope = cached public metadata such as size labels, draft state, and review-burden hints.
• Validation posture = whether the PR provides enough public validation/test evidence for maintainer review.
• Contributor workload = public contributor activity and cleanup pressure, not a repo-wide quality failure.
• Contributor context = public GitHub/Gittensor identity context; non-Gittensor status is not a blocker.
