Exclude .lychee.toml from triggering code test workflows (#2882)

## Summary

Fixes the issue where PR #2876 (docs-only changes including
`.lychee.toml`) triggered all code test workflows.

**Root cause**: `.lychee.toml` is a docs-infrastructure config file (for
the markdown link checker) but it wasn't excluded from code test
workflows in two places:

1. **Workflow `paths-ignore`**: `.lychee.toml` doesn't match `**.md` or
`docs/**`, so all code workflows triggered
2. **`ci-changes-detector` script**: `.lychee.toml` hit the catch-all
`*` pattern, which set `UNCATEGORIZED_CHANGED=true` and ran the
**entire** test suite

**Fix**:
- Added `.lychee.toml` to `paths-ignore` in all 10 code test workflow
files so they don't trigger at all
- Added `.lychee.toml` to the documentation pattern in
`ci-changes-detector` so it's classified as docs-only (defense in depth)

The `check-markdown-links.yml` workflow already correctly includes
`.lychee.toml` in its `paths:` trigger — that's the only workflow that
should care about it.

## Test plan
- [ ] Verify this PR itself only triggers `detect-changes`,
`markdown-link-check`, and `claude-review` — not code tests
- [ ] Confirm `check-markdown-links.yml` still triggers when
`.lychee.toml` changes

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Low risk: limited to CI trigger/changed-file classification logic,
with no runtime/app behavior changes; primary risk is inadvertently
skipping intended CI runs when `.lychee.toml` changes.
> 
> **Overview**
> Prevents docs-infra changes to `.lychee.toml` from triggering the main
code test suite.
> 
> Adds `.lychee.toml` to `paths-ignore` across code-related GitHub
Actions workflows (including benchmarks) and updates
`script/ci-changes-detector` to classify `.lychee.toml` as
documentation-only so it no longer falls into the catch-all “run
everything” path.

## Summary by CodeRabbit

* **Chores**
* Optimized CI workflows to treat `.lychee.toml` as a documentation-only
file, preventing unnecessary test suite triggers when only this
configuration file is modified.
