# Bug 460: strip_bot_mention fails on Element Markdown mention pill format
## Description
When Element sends a mention pill, the plain text `body` field contains a Markdown-style link like `[@timmy:crashlabs.io](https://matrix.to/#/@timmy:crashlabs.io) status`. The `strip_bot_mention` function uses prefix matching, so it tries to match `@timmy:crashlabs.io`, `@timmy`, and `Timmy` against text starting with `[` — none match. The entire message falls through to the LLM as a non-command.
`mentions_bot` works because it uses `body.contains(full_id)` which finds the MXID embedded inside the Markdown link. But `strip_bot_mention` fails because the text starts with `[`, not `@` or the display name.
This causes all deterministic bot commands (status, help, ambient, etc.) to be routed to the LLM instead of being handled by the bot when the user uses Element's mention pill (@-autocomplete).
## How to Reproduce
1. In Element, type `@timmy` and use the autocomplete pill to mention the bot
2. Append a command like `status`
3. Send the message
## Actual Result
The command falls through to the LLM. The bot logs show no "Handled bot command" entry. The plain body is `[@timmy:crashlabs.io](https://matrix.to/#/@timmy:crashlabs.io) status` which `strip_bot_mention` cannot parse.
## Expected Result
The bot should strip the Markdown mention link wrapper, extract the MXID or display name, and match the command deterministically. `@timmy status` via mention pill should produce the same pipeline status output as typing `@timmy status` manually.
## Acceptance Criteria
- [ ] strip_bot_mention handles Markdown link format `[display](https://matrix.to/#/@user:server) command` and extracts the command text
- [ ] Deterministic commands (status, help, ambient, etc.) work when invoked via Element mention pill autocomplete
- [ ] Unit tests cover the Markdown mention pill body format
- [ ] Existing strip_bot_mention tests still pass (plain @mention and display name formats)

# Bug 461: strip_bot_mention fails on Element markdown mention pill format
## Description
When Element sends a message with a mention pill, the plain text body uses Markdown link format: `[@timmy:crashlabs.io](https://matrix.to/#/@timmy:crashlabs.io) status`. The `strip_bot_mention` function in chat/util.rs uses `strip_prefix_ci` which expects the message to start with `@timmy` or the display name. Since the message starts with `[`, all prefix checks fail, the mention is not stripped, and the entire Markdown link becomes the "command name". Deterministic commands like `status`, `help`, etc. are never matched — they fall through to the LLM instead. The `mentions_bot` function works correctly because it uses `contains()` rather than prefix matching, so the bot IS triggered, but the command text extraction is broken.
## How to Reproduce
1. In Element, mention the bot using a mention pill: @botname status. 2. Element sends plain body as `[@bot:server](https://matrix.to/#/@bot:server) status`. 3. Observe that the bot routes to LLM instead of the deterministic status command handler.
## Actual Result
strip_bot_mention returns the original text unchanged. The command name is parsed as the entire Markdown link. No deterministic command matches. Message falls through to LLM.
## Expected Result
strip_bot_mention strips the Markdown mention pill `[...](https://matrix.to/...)` and returns `status`. The deterministic command handler matches and handles it.
## Acceptance Criteria
- [ ] strip_bot_mention in chat/util.rs handles the Markdown mention pill format [display](https://matrix.to/#/@user:server)
- [ ] Deterministic commands like 'status', 'help', 'overview' work when sent via Element mention pills
- [ ] Existing plain-text mention formats (@bot:server command, @bot command, BotName command) continue to work
- [ ] Tests added for Markdown mention pill format in util.rs
