Clean up orphaned probe sessions from CodexBar/ClaudeBar

[gadflysu]

Problem

CodexBar and ClaudeBar periodically spawn claude CLI to probe /usage, creating orphaned session transcripts in ~/.claude/projects/ that pollute aps listings.

• Each probe creates a .jsonl file (15KB–500KB)
• At 5-min intervals: hundreds of files, ~3.3MB observed from CodexBar alone
• These appear as valid sessions in aps

Detection

Match ~/.claude/projects/ directory names against known patterns:

Pattern	Source
*-CodexBar-ClaudeProbe*	CodexBar
*-ClaudeBar-Probe*	CodexBar (old) / ClaudeBar
*-ClaudeBar-*Probe*	ClaudeBar variants

Proposed Implementation

1. source.IsThirdPartyProbe(path string) bool — pattern matching
2. --hide-probes flag — filter out probe sessions in list/interactive mode
3. aps --clean-probes subcommand — list candidates with counts/sizes, confirm, delete
