fix: Split release process to sync pyproject.toml version with git tags (#1732)

* fix: split release process to sync pyproject.toml version with git tags (#1721)

- Split release workflow into two: release-trigger.yml and release.yml
- release-trigger.yml: Updates pyproject.toml, generates changelog from commits, creates tag
- release.yml: Triggered by tag push, builds artifacts, creates GitHub release
- Ensures git tags point to commits with correct version in pyproject.toml
- Auto-generates changelog from commit messages since last tag
- Supports manual version input or auto-increment patch version
- Added simulate-release.sh for local testing without pushing
- Added comprehensive RELEASE-PROCESS.md documentation
- Updated pyproject.toml to v0.1.10 to sync with latest release

This fixes the version mismatch issue where tags pointed to commits with
outdated pyproject.toml versions, preventing confusion when installing from source.

* Update .github/workflows/RELEASE-PROCESS.md

* fix: harden release-trigger against shell injection and fix stale docs

- Pass workflow_dispatch version input via env: instead of direct
  interpolation into shell script, preventing potential injection attacks
- Validate version input against strict semver regex before use
- Fix RELEASE-PROCESS.md Option 2 still referencing [Unreleased] section
  handling that no longer exists in the workflow
