fix(inference): sanitize route display output

[apurvvkumaria]

Summary

Sanitizes control characters in human-readable inference route output while preserving raw provider and model values for JSON output and programmatic callers. This is the upstream replacement for #7165 so required trusted CI and credentialed E2E can execute; the implementation remains credited to original author HwangJohn.

Changes

• Sanitize provider and model fields only at the human-readable display boundary.
• Preserve raw route values in returned objects and JSON output.
• Add regression coverage for control characters and raw-value preservation.

Type of Change

• Code change (feature, bug fix, or refactor)
• Code change with doc updates
• Doc only (prose changes, no code sample modifications)
• Doc only (includes code sample changes)

Quality Gates

• Tests added or updated for changed behavior
• Existing tests cover changed behavior — justification:
• Tests not applicable — justification:
• Docs updated for user-facing behavior changes
• Docs not applicable — justification: the command shape and documented behavior are unchanged; this hardens terminal rendering only.
• Sensitive paths changed (security, policy, credentials, preflight, onboarding, inference, runner, sandbox, or messaging)
• Sensitive-path review completed or maintainer-approved waiver recorded — reviewer/approval link/justification: the change is confined to the display boundary, and tests verify raw values remain intact for JSON and programmatic callers.
• Non-success, skipped, or missing CI check accepted by maintainer — check name, approval link, and follow-up issue:

Verification

• PR description includes the DCO sign-off declaration and every commit appears as Verified in GitHub
• Git hooks passed during commit and push, or npx prek run --from-ref main --to-ref HEAD passes
• Targeted tests pass for changed behavior — 5/5 inference-get tests
• Full npm test passes (broad runtime changes only)
• Quality Gates section completed with required justifications or waivers
• No secrets, API keys, or credentials committed
• npm run docs builds without warnings (doc changes only)
• Doc pages follow the style guide (doc changes only)
• New doc pages include SPDX header and frontmatter (new pages only)

Summary by CodeRabbit

• Bug Fixes
  • Improved inference output readability by sanitizing control and escape characters in displayed provider and model values.
  • Preserved raw provider and model values for programmatic responses.
  • Continued displaying “unknown” when no usable provider or model value is available.

📝 Walkthrough

Walkthrough

Inference logging now sanitizes provider and model route values for human-readable output while preserving raw values in the resolved result. A unit test covers control and escape character handling.

Changes

Inference display sanitization

Layer / File(s)	Summary
Sanitized logging and regression coverage src/lib/actions/inference-get.ts, src/lib/actions/inference-get.test.ts	The logging path formats provider and model values with route sanitization and an "unknown" fallback, while tests verify raw return values and sanitized log output.

Exact-head maintainer audit on 184172d: the display-only sanitizer is applied after route parsing, while raw provider/model values remain unchanged for JSON and programmatic callers. Focused inference/config coverage passes 60/60, CLI type-check passes, the commit is GitHub Verified with DCO and original-author credit, all CI/advisors/protected E2E are green, and there are no unresolved review threads. No blocking security or correctness issue found. Independent review requested from @cv because the PR is authored by the current maintainer account.
