fix: address Copilot review feedback round 5

Addresses review #3737525469:

1. README badge: Changed from hardcoded repo URL to link to devcontainer
   docs, so forks don't redirect to upstream repo

2. Aliases: Use dedicated ~/.bash_aliases file instead of modifying
   ~/.bashrc with sed, avoiding potential accidental content deletion

3. Volume mount: Fixed from ../.. to ../workspaces/go-sqlcmd to only
   mount the repo root, not parent directories that could expose secrets

4. MSSQL connection: Removed hardcoded password from mssql.connections
   config. Users will be prompted to enter password on first connect.

5. Password handling: Added environment variable substitution support:
   - docker-compose.yml: Uses SQLCMDPASSWORD env var with default
   - devcontainer.json: Uses localEnv with fallback to default
   - Added comments explaining this is dev-only, not production secrets
   - Updated README to clarify password is available via env var
