chore: bump llama.cpp to b10450; 1.0.10438:0 → 1.0.10450:0

[helix-nine]

Summary

Bumps llama.cpp from build b10438 to b10450 — 12 upstream commits. StartOS version 1.0.10438:0 → 1.0.10450:0.

All four image variants were confirmed published on GHCR before pinning (server-, server-cuda-, server-rocm-, server-vulkan- at b10450), with the expected arches (rocm x86-only, the rest amd64+arm64).

Upstream highlights

• Adds the Kimi-K3 text model family.
• server: the yield_to_queue thread model was re-designed, improving behaviour under concurrent requests.
• Vulkan: coopmat1 tuning for Intel Xe, plus fixed gating for a problematic Intel driver version.
• Built-in chat UI: the API key field is masked so browsers stop offering to save it; MCP tool results now read structuredContent when content is empty.
• GGUF parsing now checks array types before reading (malformed metadata is rejected rather than misread).
• --models-dir can load MTP assistant models.
• Vendored cpp-httplib → 0.53.1 and BoringSSL → 0.20260813.0.

Deprecation checked, no package change needed

Upstream deprecated --mmap / --no-mmap / --mlock / --direct-io in favour of -lm/--load-mode (#26934). They still parse and only emit a warning, so nothing breaks. This package builds its serve args from -hf, -hff, -c, -ngl, --host and --port only, so none of the deprecated flags are used by main.ts or the presets; the release notes mention it for users who pass them via Set Model's extra arguments.

The presets in startos/actions/presets.ts were reviewed against the range — no flag renames or server-API changes affect them.

Other

• @start9labs/start-sdk is already at the latest published version (2.0.9) — no SDK bump.
• No *-startos git dependencies, so no dependency refresh.

Test plan

• npm run check (tsc) — green.
• Registry checked: latest published is 1.0.10380:0, so 1.0.10450:0 is free.
• make generic / full build verification left to review, per the monitor-cycle policy.

Superseded by #22, which now carries this bump.

#22 (Set Model prefill) and this one both rewrote startos/versions/current.ts, so they could not both land — and shipping them as two releases would have meant 1.0.10438:1 immediately followed by 1.0.10450:0. Cherry-picked 92c6ce8 onto #22 instead (authorship preserved), resolved to this branch's current.ts, and folded the Set Model item into the release notes as its own section. Final version is 1.0.10450:0 with the b10450 upstreamBuild, unchanged from what this PR proposed.

next still carries 92c6ce8, so it will be a no-op once #22 merges — drop it on the next rebase.
