chore: release 0.7.7

Hotfix release for #116: pinning ort to =2.0.0-rc.11 so users
running \`cargo install ck-search\` (without --locked) don't
get 36 compile errors from a rc.12 upgrade they didn't ask for.

+### Fixed
+- **`cargo install ck-search` failed with 36 errors out of `ck-embed::mixedbread`** (#116, reported by @gianpaj). `cargo install` (without `--locked`) ignores `Cargo.lock` and re-solves from scratch; the workspace's `ort = "2.0.0-rc.11"` was a caret range that let cargo pick the newer `2.0.0-rc.12`. rc.12 made `SessionOptionsPointer: !Sync`, which removed `Send + Sync` from `ort::Error<SessionBuilder>` and broke every `?`-conversion into `anyhow::Error`. Pinned to `=2.0.0-rc.11` so any resolution path (locked or not) lands on the tested version. Upgrade to rc.12 will be evaluated in a follow-up.
