fix: coder mount paths and npm ci improvements (#423)

* fix: remove unnecessary coder binary move step in deployment workflow

* fix: clean node_modules before npm ci in post-create script

Ensures npm ci succeeds by removing existing node_modules before
installation. This prevents fallback to npm install and ensures
reproducible, faster installations using package-lock.json.

Changes:
- Add rm -rf node_modules before root npm ci
- Add rm -rf node_modules before frontend npm ci

* fix: update coder mount paths to use isolated subdirectories and /root

- Update all host paths to use isolated subdirectories per tool
  (e.g., claude/.claude, gemini/.gemini, ssh/.ssh)
- Change all container paths from /home/vscode/ to /root/
- Update environment variables (HISTFILE, GIT_CONFIG_GLOBAL) to /root/
- Add direct mount for claude.json instead of symlink
- Remove symlink creation from post-start.sh

This ensures proper isolation and consistency for Coder workspaces.

* fix: use .claude.json (with dot) for host path consistency

Match exact filename on both host and container paths.

* fix: use unique version names for coder template pushes

Generate version names using timestamp and commit SHA to avoid
duplicate version name errors in CI/CD pipeline.

Format: v{YYYYMMDD-HHMMSS}-{commit-sha}
Example: v20260101-143025-f642fb0

Also activates the new version automatically.
