Subject: [PATCH 14/38] feat: implement AST-based Telegram formatting and
 native Gemini session management

- Replace regex-based Markdown parsing with goldmark AST renderer in Telegram bot
- Implement native /resume and /resume  commands for ssls and sssw
- Clean up obsolete session file reading logic in Gemini adapters
- Fix Windows-specific test failures in logger and cli adapters

Subject: [PATCH 16/38] fix: implement ssls/sssw for ACP sessions via shared
 file-scan helper

- Refactor ListSessions/SwitchSession into shared package-level functions
- ACPAdapter.ListSessions reads workDir from acpSession struct (no tmux needed)
- ACPAdapter.SwitchSession sends /resume  via ACP input channel
- Remove old stubs that returned 'handled natively' errors

Subject: [PATCH 19/38] feat: standardise Gemini session ID format across ssls
 and status bar

- 'ssls' now prints 12-char short IDs wrapped in backticks (e.g. \#e96ee943-179\) for easy clicking/copying in Telegram
- 'sssw' now accepts short ID prefixes and resolves them to full UUIDs automatically in both Hook and ACP modes

-**Special Keywords** (exact match, case-insensitive):
-  ⚠️ These keywords only work in Hook mode with tmux input
-  tab            - Send Tab key
-  esc            - Send Escape key
-  stab/s-tab     - Send Shift+Tab
-  enter          - Send Enter key
-  ctrlc/ctrl-c    - Send Ctrl+C (interrupt)
-  ctrlt/ctrl-t    - Send Ctrl+T

-**Usage Examples:**
-  status            → Show status
-  tab               → Send Tab key to CLI
-  ctrl-c            → Interrupt current process
-  ctrl-t            → Trigger Ctrl+T action
-  snew myproject claude ~/work  → Create new session
-
-**Tips:**
-  - Special commands are exact match (case-sensitive)
-  - Special keywords are case-insensitive
-  - Any other input will be sent to the CLI
-  - Use "suse" to switch between sessions
-  - Use "sclose" to free up resources when not using a session
-  - Use "sstatus" to monitor session health and resource usage
