Add a per-room/global `sender_context_mode` setting that optionally
prefixes conversation messages with sender metadata before sending them
to the model provider.
This helps models distinguish between participants in multi-user rooms.
Three modes are supported:
- `disabled` (default, no change)
- `matrix_user_id` (prefixes with `[sender=@user:server]`)
- `matrix_user_id_and_timestamp` (adds `send_at`; Example: `[sender=@user:server sent_at=<ISO 8601>]`)
Sender context is applied to user and assistant text messages only,
skipping system prompts and non-text content.
Mixed-sender merged turns (something we intentionally do for Anthropic)
have their `sender_id` cleared to avoid misattribution.
async-openai 0.34 adds a required phase field to EasyInputMessage,
which broke our Responses API request construction.
Set phase to None because baibot does not currently model assistant commentary vs final-answer turns,
so omitting phase preserves the previous behavior while keeping the request compatible with the new crate.
Files with unrecognized MIME types (application/octet-stream) are
not supported by any LLM provider and would cause errors that
permanently break the conversation thread. Instead, represent them
as a text message describing the attachment so the LLM is still
aware a file was sent without the thread becoming unusable.

Replace the hand-maintained extension-to-MIME mapping with the
mime_guess crate, which was already in the dependency tree.
This covers hundreds of file extensions out of the box.

Files sent as m.file Matrix messages are now downloaded, MIME-detected,
and forwarded to LLM providers alongside the conversation context,
similar to how m.image is already handled.
- OpenAI provider: sends files inline as base64 data URLs
- Anthropic provider: skips files with a warning (library limitation)
- OpenAI-compat provider: skips files with a warning (library limitation)
Controller routing respects the existing prefix requirement setting.
MIME detection expanded to cover PDF, text, code, and document formats.
Docs updated to reflect file support and known limitations.

Add the 1.15.0 changelog entry covering access-token authentication support, Rust 1.93.0 toolchain pinning, docs updates, and dependency updates. Bump crate version to 1.15.0 in Cargo.toml and Cargo.lock.
Add a dedicated configuration/authentication doc covering password and access-token setup,
including environment-variable mappings and token-generation example.
Link to it from configuration docs and align the sample config wording with Matrix Authentication Service/OIDC terminology.
