When Claude sessions were terminated using KillSession(), bash subprocesses
spawned by Claude's Bash tool could survive because they ignore SIGHUP.
This caused zombie processes to accumulate over time.
Changed all critical session termination paths to use KillSessionWithProcesses()
which explicitly kills all descendant processes before terminating the session.

* test(util): add comprehensive tests for atomic write functions
Add tests for:
- File permissions
- Empty data handling
- Various JSON types (string, int, float, bool, null, array, nested)
- Unmarshallable types error handling
- Read-only directory permission errors
- Concurrent writes
- Original content preservation on failure
- Struct serialization/deserialization
- Large data (1MB)
* test(connection): add edge case tests for address parsing
Add comprehensive test coverage for ParseAddress edge cases:
- Empty/whitespace/slash-only inputs
- Leading/trailing slash handling
- Machine prefix edge cases (colons, empty machine)
- Multiple slashes in polecat name (SplitN behavior)
- Unicode and emoji support
- Very long addresses
- Special characters (hyphens, underscores, dots)
- Whitespace in components
Also adds tests for MustParseAddress panic behavior and RigPath method.
Closes: gt-xgjyp
* test(checkpoint): add comprehensive test coverage for checkpoint package
Tests all public functions: Read, Write, Remove, Capture, WithMolecule,
WithHookedBead, WithNotes, Age, IsStale, Summary, Path.
Edge cases covered: missing file, corrupted JSON, stale detection.
Closes: gt-09yn1
* test(lock): add comprehensive tests for lock package
Add lock_test.go with tests covering:
- LockInfo.IsStale() with valid/invalid PIDs
- Lock.Acquire/Release lifecycle
- Re-acquiring own lock (session refresh)
- Stale lock cleanup during Acquire
- Lock.Read() for missing/invalid/valid files
- Lock.Check() for unlocked/owned/stale scenarios
- Lock.Status() string formatting
- Lock.ForceRelease()
- processExists() helper
- FindAllLocks() directory scanning
- CleanStaleLocks() with mocked tmux
- getActiveTmuxSessions() parsing
- splitOnColon() and splitLines() helpers
- DetectCollisions() for stale/orphaned locks
Coverage: 84.4%
* test(keepalive): add example tests demonstrating usage patterns
Add ExampleTouchInWorkspace, ExampleRead, and ExampleState_Age to
serve as documentation for how to use the keepalive package.
* fix(test): correct boundary test timing race in checkpoint_test.go
The 'exactly threshold' test case was flaky due to timing: by the time
time.Since() runs after setting Timestamp, microseconds have passed,
making age > threshold. Changed expectation to true since at-threshold
is effectively stale.

Implement MachineRegistry that manages machine configurations and
provides Connection instances for local and remote operations:
- Machine struct with name, type, host, key path, and town path
- Registry with JSON persistence (federation.json)
- CRUD operations: Get, Add, Remove, List
- Connection factory that returns appropriate Connection type
- Built-in "local" machine that cannot be removed
SSH connections return an error until SSHConnection is implemented.

Define the Connection interface that abstracts file operations, command
execution, and tmux management for both local and remote (SSH) contexts.
Includes:
- Connection interface with file, exec, and tmux operations
- FileInfo interface for remote stat results
- BasicFileInfo implementation with JSON serialization
- Error types for connection failures
This enables Gas Town to manage rigs on remote machines using the
same interface as local operations.
