A live token-scope probe against mathias/ai-sessions revealed gitea's
contents API uses POST to create and PUT (sha required) to update — the
first impl always PUT'd, so creating a new summary 422'd "[SHA]: Required".
The httptest mock had the same wrong assumption. Pick the method by
whether the file exists (GET sha). Token confirmed contents:write
(push:true) by the probe.

Adds Client.WriteFile (Gitea contents API) so the Gitea client also
implements capture.SummaryWriter. Upserts: a GET resolves the current
blob sha so an existing file is updated (the richer-fidelity-supersedes
rule for re-captured sessions) rather than 422'd. Owner stays the fixed
const; token only in the Authorization header (no leak — regression
tested). Refactors the HTTP path into a shared request() helper so the
contents flow can branch on 404 without it being an error.

Implements the IssueTracker port as a real Gitea REST client (#49c) — the
new outbound dependency the brain server gains for capture.
- CreateIssue / CommentIssue / CloseIssue(+optional closing comment) over
the Gitea API. Owner is the const "mathias", never caller-supplied, so
a caller cannot redirect a write to another owner's repo.
- Token read once at construction (BRAIN_GITEA_TOKEN), held in the struct,
travels only in the Authorization header — never logged or in argv.
Error messages carry status + truncated body, never the token
(regression-tested). gitea.New returns nil when URL or token is unset,
so missing config = tracker disabled via one nil check.
- Injected into the MCP server behind the capture.IssueTracker interface
via WithIssueTracker (constructor injection, swappable/testable); main
wires it from BRAIN_GITEA_URL (default https://git.d-ma.be) +
BRAIN_GITEA_TOKEN. Consumed by the capture use-case in #53.
Tests use httptest transports: create (owner+auth header asserted),
comment, close with/without comment, error path that proves the token
never leaks into an error string.
