Expose server metadata in Server initializer - #258

Issue titles are now bare 'Upstream PR#<n>'; the merge/investigate/decline
label carries the decision, so the title does not duplicate it. Two places
named the old convention and are updated.

The investigate count was also stale: it said twelve, which was true at
triage on 2026-09-10. Four were declined since (modelcontextprotocol#280, modelcontextprotocol#226, modelcontextprotocol#118, modelcontextprotocol#204) and
two were promoted and merged (modelcontextprotocol#266 as entries 9/9a, modelcontextprotocol#275 as 10/10a/10b),
leaving six — modelcontextprotocol#178, modelcontextprotocol#213, modelcontextprotocol#216, modelcontextprotocol#257, modelcontextprotocol#258, modelcontextprotocol#259 — now listed by number
rather than by count, so the sentence cannot drift again.

Upstream PR modelcontextprotocol#258 (yonaskolb), head adcb230.

The convenience Server.init accepted name/version/title/instructions and
built a Server.Info that silently dropped description, websiteUrl and
icons -- fields Server.Info already declares and the 2025-11-25 spec
already carries in serverInfo. Before this they were reachable only by
constructing Server.Info by hand.

Additive and non-breaking: the three new parameters default to nil and
sit between title: and instructions:, so existing call sites are
unaffected. Client.init already forwarded the same three to Client.Info,
so this closes an asymmetry rather than opening one.

No adaptation; merged as authored.

Expose server metadata in the Server initializer. Moves the entry out of
the candidates table into the manifest, corrects the investigate count to
five, and pins the usage example to the tag cut from this commit.

…ests without a reply (upstream modelcontextprotocol#298, EhsanAzish80)

Supersedes the contributions of modelcontextprotocol#264, modelcontextprotocol#260 and modelcontextprotocol#270 (manifest entries 1-3),
which modelcontextprotocol#298 combines. Conflicts resolved in favour of modelcontextprotocol#298 in
HTTPServerTypes.swift, StatelessHTTPServerTransport.swift, Server.swift,
CancellationTests.swift and HTTPServerTransportTests.swift.

Fork changes re-applied on top:
- modelcontextprotocol#258's Server.init description/websiteUrl/icons parameters
- modelcontextprotocol#221's MockTransport receiveCallCount / finishStream
- entry 1a's collision regression tests and their makeStatelessPOSTRequest
  authorization overload

Behavior: a cancelled original POST now ends as HTTP 200 with an empty
text/event-stream and no JSON-RPC body (previously -32002 from modelcontextprotocol#260).
Follow-up on when to use -32800: fork issue #41.

Full suite: 589 tests in 43 suites passed.

…rder

Entry 3a broke two conventions: letter suffixes mark fork additions, and
the Order column claims merge order, in which modelcontextprotocol#298 comes after modelcontextprotocol#258. The
maintenance procedure now says to skip superseded rows.
