Handle edge case where Claude's --resume creates an orphan session file
before resuming the original session, leaving two session files pointing
to the same Zellij pane.
The deduplication algorithm (_dedupe_same_pane_sessions) resolves
conflicts by preferring:
1. Sessions with context_usage (indicates actual conversation occurred)
2. Higher conversation_mtime_ns (more recent file activity)
When an orphan is identified, its session file is deleted from disk to
prevent re-discovery on subsequent state collection cycles.
Test coverage includes:
- Keeping session with context_usage over one without
- Keeping higher mtime when both have context_usage
- Keeping higher mtime when neither has context_usage
- Preserving sessions on different panes (no false positives)
- Single session per pane unchanged
- Sessions without pane info unchanged
- Handling non-numeric mtime values defensively

Position the spawn modal directly under the 'New Agent' button without a
blur overlay. Uses click-outside dismissal and absolute positioning.
Reduces visual disruption for quick agent spawning.
Closes bd-3ny. Added mousedown listener that dismisses the dropdown when
clicking outside both the dropdown and textarea. Uses early return to avoid
registering listeners when dropdown is already closed.
Adds comprehensive test coverage for the amc_server package:
- test_context.py: Tests _resolve_zellij_bin preference order (which
first, then fallback to bare name)
- test_control.py: Tests SessionControlMixin including two-step Enter
injection with configurable delay, freeform response handling,
plugin inject with explicit session/pane targeting, and unsafe
fallback behavior
- test_state.py: Tests StateMixin zellij session parsing with the
resolved binary path
