Tracks upstream lmcp v1.0.0-rc1 (commit deb73d1).

Surface

Arch (arch/lmcp/PKGBUILD):

pkgver=1.0.0_rc1 (Arch '_' substitutes for '-' in pre-release tags)
_tag="v${pkgver//_/-}" back-translates for the archive URL
sha256 bumped

Debian (debian/lmcp/build-deb.sh, debian/lmcp/debian/changelog):

PKGVER=1.0.0~rc1 (Debian '~' sorts before the release)
UPSTREAM_TAG=v1.0.0-rc1 drives the archive URL
changelog entry summarises the release

What's in 1.0.0-rc1

14 upstream issues closed (#3, #4, #5, #6, #7, #8, #9, #10, #12, #13, #14, #15, #16, #19)
New MCP primitives: Resources, Prompts, Completion, Logging, Sampling, Roots, plus the fetch and web_search tools
Protocol: cursor pagination, structuredContent, _meta passthrough, tool annotations (readOnlyHint/destructive/idempotent/openWorld), protocolVersion bump to 2025-06-18
Transports: stdio (LMCP_TRANSPORT=stdio) for Claude Desktop / IDE clients; full Streamable HTTP rewrite (select()-based event loop, sessions, persistent SSE, server-initiated requests, DELETE, heartbeat)
json.lua: UTF-16 surrogate-pair combination + json.empty_object sentinel for spec-correct {} emission
Backwards-compatible with every existing sessionless-POST client

Honest limits (filed as upstream follow-ups)

#11 progress/cancellation — gated on #20 (handler concurrency)
#18 windows/pkg/ packaging sync — stale snapshot
#20 concurrent handler dispatch — select() loop multiplexes I/O but synchronous tool handlers still serialise

Test plan

CI build (arch + debian) succeeds with the new sha256
Install on hertz (Arch) and a Debian host; lmcp --version reports new version (via lmcp-example server name string is the closest proxy today)
Smoke: LMCP_TRANSPORT=stdio works end-to-end
Existing hub deployments still talk to upgraded backends (sessionless-POST backwards compat)
