fix(ci): make MCP server default bump target for all non-scoped commits

BREAKING CHANGE: MCP server now bumps for ANY conventional commit except
those explicitly scoped to helm or astrolabe.

Previous behavior:
- MCP bumped only for unscoped or scope=mcp commits
- fix(ci): commits were ignored → no version bump

New behavior:
- MCP bumps for ALL commits except scope=helm or scope=astrolabe
- fix(ci): commits now trigger MCP version bump ✓
- feat(api): commits now trigger MCP version bump ✓
- Any custom scope triggers MCP version bump ✓

This treats the MCP server as the default/primary component in the
monorepo, with Helm chart and Astrolabe as opt-in specialized components.

Changes:
1. Updated bump-version.yml workflow logic to exclude helm/astrolabe
   instead of only including mcp/unscoped
2. Updated pyproject.toml commitizen patterns to use negative lookahead:
   (?!\((?:helm|astrolabe)\))
3. Fixed docker-build-publish.yml to only trigger on v* tags (MCP only)
4. Fixed appstore-build-publish.yml action version (v1.0.4)
5. Updated test script to use grep -P for PCRE support
6. Added test cases for ci, api, and custom scopes

All 19 scope filtering tests now pass.
