* fix(mantis): bound upload error response bodies
Replace unbounded response.text() on non-ok upload error paths with
readBoundedResponseText (64 KiB cap). Only swallow the size-exceeded
diagnostic; propagate signal aborts and other failures so timeouts
during body reading are not masked as generic upload failures.
- Import shared readBoundedResponseText from scripts/lib/bounded-response.mjs
- Add MANTIS_UPLOAD_ERROR_BODY_MAX_BYTES constant (64 KiB)
- Catch only size-exceeded errors; re-throw timeouts and stream errors
- Add test: oversized body bounded at 64 KiB
- Add test: signal abort during body read propagates correctly
- Add test: small error body within bound reads normally
* fix(mantis): contextualize bounded upload failures
