Bump version to 0.1.12 and resume per-PR patch bumps

[realproject7]

Problem

Version has been stuck at 0.1.11 since PR #571. 12 PRs merged without a patch bump, violating the versioning rule in CLAUDE.md.

Fix

1. Bump package.json version to 0.1.12
2. Resume bumping patch version in every subsequent PR going forward

Reminder

Per CLAUDE.md versioning rules:

• 3rd digit (patch): T3 bumps autonomously per PR
• 2nd digit (minor): T1 permission required
• 1st digit (major): T1 permission required

Branch

task/596-version-bump

Acceptance criteria

• package.json version set to 0.1.12
• Build passes
