Addresses findings from an independent review of the gap-closing commits:
- R1 (regression): add #[serde(default)] to HttpDispatchPayload.method so
async-HTTP outbox rows enqueued before the field existed still decode
after upgrade instead of dead-lettering on "missing field `method`".
Adds a regression test for the missing-key path.
- method case: uppercase ctx.request.method at the orchestrator boundary
so it honors its documented "uppercased" contract for extension verbs.
Route matching is already case-insensitive, so matching is unaffected.
- CLI hardening: percent-encode free-form path segments (app slug, topic
name, ids, secret name) in the reqwest client so a value containing
`/ ? #` can't break out of its URL segment. Adds a `seg()` helper +
unit test and applies it uniformly across all path-interpolating
methods (new and pre-existing).
- S1 (docs): correct the users::email_available enumeration framing — it
adds no new vector vs. create's uniqueness error, but is cheaper and
unthrottled; there is no built-in throttle/CAPTCHA primitive, so the
honest mitigation is a kv-based counter. Updated SDK doc-comments,
trait docs, and stdlib-reference.
