- schema: add crash/report.type conditionals (allOf if/then) so a
crash/anr/native_crash/hang/abnormal_exit manifest requires `crash`
and a `manual` manifest forbids it, matching ValidateManifest.
- service: reject uploads where X-Profile-Id and manifest.report.profile_id
are both present but differ (new ErrProfileMismatch, mapped to 400
profile_mismatch) instead of silently preferring the header; single-source
and matching cases unchanged. Adds service tests for mismatch, match, and
header-only attribution.
- schema: require manifest.json as the first archive.entries element via
prefixItems (contains retained for validators without prefixItems support).
- schema: document that maxLength is a character-count bound while the server
enforces UTF-8 byte length, via a top-level note and per-field notes on the
free-text device_summary and crash fields.

Implements slice 1 of docs/design/2026-07-19-client-diagnostics.md: the
versioned contract (schemas, fixtures, Go validator), storage-validated
diagnostics.uploads_enabled gate, account-scoped status endpoint, hardened
streaming multipart ingest with quota reservation and a receiving/ready/
failed report state machine, S3 streaming puts, acting-admin report API
(list/detail/download/delete with audit events), and the retention +
orphan-reconciliation cleanup task.
