docs: update CLAUDE.md spec-spine pin reference to 0.10.0

[bartekus]

Follows the 0.8.0 to 0.10.0 bump in #10. CLAUDE.md documented the pin as 0.8.0; this was the only stale version reference (verified by grep). Doc-only, no owned-path change.

Review: CLAUDE.md version-string update

Bugs / Logic Errors

None. The change is a single documentation string update.

Security

Not applicable — no executable code touched.

Spec-spine Compliance

The actual package.json / package-lock.json bump to 0.10.0 landed in the prior commit (2d0e68a). This commit (c0311d2) simply keeps CLAUDE.md from lying about the pinned version. No spec-claimed code path changed, so no owning .spec.md update is required and no coupling gate concern exists.

One minor observation: CLAUDE.md is the canonical human-readable reference for the pin, so keeping it in sync is correct. There are no other copies of the version string in CLAUDE.md that were missed (only one occurrence).

Performance

Not applicable.

Verdict: No issues. The diff is a one-line doc fix with no functional surface.
