Bump plugin version to 0.1.4 so downstream projects pick up the fixes

[robercano]

What

Bump the orchestrator plugin version from 0.1.3 to 0.1.4 so downstream projects that update the plugin receive the fixes merged since the last release — in particular the pr-loop-self downstream-exposure fix (#76 / PR #77).

Ordering

Do this AFTER PR #77 (fix for #76) is merged, so the release actually contains the fix. If #77 is still open when this issue is picked up, skip and wait for the next tick.

Where the version lives

Same files as the previous bump (PR #67, chore/bump-0.1.3):

• .claude/.claude-plugin/plugin.json — version field (1 occurrence)
• .claude/.claude-plugin/marketplace.json — version fields (2 occurrences)

All three must be updated to 0.1.4 in lockstep.

Acceptance

• grep -rn "0\.1\.3" .claude/.claude-plugin/ returns nothing; all three version fields read 0.1.4
• The commit lands on main after the Plugin ships self-hosting-only /pr-loop-self command to downstream projects #76 fix, so a downstream /orchestrator:sync (or plugin update) at 0.1.4 no longer ships pr-loop-self
