feat(session): implement session expiration with configurable timeout (#84)
* Reapply "feat(session): implement session expiration with configurable timeout (#83)"

This reverts commit 1ba55a4b9c.

* fix(session): address code review feedback

- Fix integer overflow: return -1 from get_session_file_age_hours on stat
  failure instead of 0, preventing false expiration
- Handle stat failure in init_claude_session with WARN log
- Add comprehensive documentation for return values and expiration strategy
- Add 6 behavioral integration tests that verify actual functionality
- Add inline comments explaining 24-hour default rationale

Test count: 286 → 292 (100% pass rate)

* fix(test): use grep-based verification to fix CI failures

Tests that sourced ralph_loop.sh with --help flag failed in GitHub
Actions due to BATS environment differences. Changed behavioral tests
to grep-based code verification that checks implementation patterns
exist without executing the script.

* fix(test): guard main with BASH_SOURCE for safe sourcing

- Add BASH_SOURCE check to only execute main when script is run directly
- Update tests to source script without --help flag
- Convert grep-based verification tests back to functional tests
- Fixes CI failures caused by script execution during sourcing
