fix(config,cli,tui): move the correx server off :8080 to :8090 (#695)

mavgpud.service, the Maven GPU supervisor, is an enabled systemd user unit that
binds *:8080 and restarts on kill. The correx server wanted the same port, so
qa-stack died with BindException and the QA stack never came up. Worse,
qa-stack's --stop ran `fuser -k 8080/tcp`, which killed mavgpud rather than a
correx server; systemd then restarted it straight into the port it had just
freed, so it won the race every time.

Moves the default to 8090 in the four places that have to agree: ServerConfig,
ConfigLoader's fallback, the CLI's DEFAULT_PORT, and the TUI's -port flag. A
mismatch between any two of them is a client that cannot find its own server.

The machine-local halves are not in this diff and were applied on disk:
`~/.config/correx/config.toml` pinned `port = 8080` explicitly, which overrides
the code default, and `scripts/` is gitignored so qa-stack.sh's five references
(including the --stop kill, now aimed at 8090) live only on this box.

Verified live: the server binds 8090 and answers /health while mavgpud keeps
8080. Left open in #695: mavgpud also spawns a llama-server on :10000, which is
qa-stack's router port, and qa-stack pkills that pattern.

- * the failure text is frozen for the whole tool loop: the agent edits the offending file, is told
- * "written successfully", and keeps editing against a diagnostic it may already have cleared — it
- * only finds out after `stage_complete`, when [runPostStageGates] re-runs from the top. Called from
- * the existing `wroteThisRound` hook, this re-pulls diagnostics and records them, so
- * [buildRetryFeedbackEntry]'s per-file ledger flips to "done, leave it" in-loop. Rebuilding from the
- * recorded event (invariant #9) is what keeps the fresh truth replayable, and is why there is no new
- * message format here.
- *
- * Scoped to LSP by design: a `tsc` / `npm run build` re-run per write is too expensive. Fires only
- * when the write landed on a path the frozen failure actually names, so an unrelated write in the
- * same loop costs nothing.
- *
- * Returns the rebuilt `retryFeedback` entry, or null when nothing applies (no runner, wrong gate, no
- * overlap, or the pull was skipped). Returns null on a skipped pull deliberately: an empty
- * diagnostics list from a server that never started reads as "clean" to the ledger, and telling the
- * model to leave a still-broken file alone is worse than leaving the stale text in place.
