The bot serves an HTTP API beside the chat client, in the new package `internal/api`, routed with chi. `internal/config` reads `PORT` and the credential in the file named by `API_TOKEN_FILE`. `bot.Run` starts the API once set-up is done and stops it, with up to 5 seconds for requests in progress, when it returns; a listener failure ends `Run` with an error. The image `EXPOSE`s 8080 only. Every response carries the issue's security headers and also `Permissions-Policy`, which `docs/REPO_POLICIES.md` requires, denying the camera, microphone and location.

The bot now serves an HTTP API on PORT (default 8080) beside the chat
client. Every request needs the credential read at startup from the
file named by API_TOKEN_FILE, sent as a bearer token; without one,
every request is refused. Responses carry the security headers, bodies
are capped at 64 KiB and each request's work at 10 seconds.
GET /api/v1/chats lists the bot's contacts from the chat client's
/_contacts command, ordered by id, and marks the contacts who deleted
their chat with the bot, which the chat client keeps listing. bot.Run
starts the API after set-up and stops it within 5 seconds; a listener
failure ends the bot as a chat client failure does.

The earlier Permissions-Policy finding is resolved. One new finding:
internal/bot/bot.go, Run, the comment on defer stopAPI, and the README's Design entry for the API ("When the bot stops, requests in progress get 5 seconds to finish"). Both say a request in progress finishes while the chat client is still there to answer it. It does not. The chat client runs under a context derived from ctx, so it gets SIGTERM the moment the bot is told to stop, while the API is only starting its graceful stop. A request waiting on the chat client at that moment gets 500{"error":"the chats could not be read"} instead of its answer. #4 asks for the API to stop gracefully, and the next unit, sending a message, inherits this order. Acceptable: signal the chat client only after stopAPI returns. For example, stop cancelling the chat client's context through ctx and cancel it in the deferred stop, which runs after stopAPI. Then the comment and the README are true. Failing that, the comment and the README must say what actually happens.

The chat client's context no longer follows the bot's, so a stop no
longer sends it SIGTERM while the API is still finishing its requests.
The deferred stop in Run, which runs after the API's, stops it instead,
so a request in progress at a stop gets its answer rather than a 500.
The README says so.
The new test runs the whole bot with the test binary itself standing in
for simplex-chat on PATH. The stand-in holds its answer to the contacts
request until the test has told the bot to stop.

Fixed in 407eaf847a, with a test that runs the whole bot and gets 200 for a request in progress when the stop begins.
Judgement call: the test's stand-in chat client takes the chat client's fixed port 5225 on the host, so two runs of that test at once on one machine collide.

The PR discloses only that two runs of the test collide. The worse case: with a real simplex-chat on 5225 (the port the SimpleX documentation uses for it), make test sends that client the bot's set-up commands, which create an address on that profile if it has none and set it to accept every contact request and greet with the calculator's welcome. A test must never reach a program outside itself. Acceptable: the stand-in listens on a port the test picked free, never 5225; for example, Run takes the chat client's port from its caller, the run command passing 5225 and the test a free port, with no new environment variable.
Judgement call: the longest stop of 15 seconds, beyond docker stop's default 10, needs no --stop-timeout in the README: it is reached only when the chat client is itself slow to stop, and then docker stop kills it at most 5 seconds before the bot would.

net/http answered "OPTIONS *" itself, with 200, before the router, so
it skipped the credential check and the security headers. The server
now passes it to the router, which refuses it with 401 like any other
request without the credential. A test sends it to a running server,
since the handler alone never sees it.
Model: opus-5-5
Fixed in 0c5163e69e: the server now hands OPTIONS * to the router, and a new test sends it without the credential to a running server.
Checked in net/http's server code: apart from OPTIONS *, it answers only requests it cannot parse or serve before the router sees them. That means a malformed request line or header or a missing or malformed Host (400), an HTTP version other than 1.x (505), headers over the size limit (431), an unknown Transfer-Encoding (501), and an Expect other than 100-continue (417). Each is a refusal with an empty body or net/http's own fixed reason. None echoes the request, reveals anything about the bot or changes state, so none lets a request through.
Judgement call: those refusals still go out without the security headers. No server setting hands them to the router, and adding the headers would mean rewriting the connection's bytes, so I left them as they are.
