Align claude-code-action version between claude-invoke and downstream workflows

[benhigham]

Problem

The claude-invoke composite action pins anthropics/claude-code-action@3ac52d0d while downstream workflows that call the action directly (claude-code-review.yml, claude.yml in benhigham/web) pin @88c168b3. This version skew means workflows doing the same kind of work (invoking Claude) may behave differently.

Surfaced during review of benhigham/web#150.

Suggested fix

Bump claude-invoke's pinned claude-code-action SHA to match the version used by the non-migrated workflows, or update all references to the latest release at once.

Context
