feat(search): document and validate calibrated effort tiers (#4882)

Browse Source 
Lance beta.11 calibrates lower `search_effort` tiers by metric and
requested `k`. With the Rust dependency and Python/Node execution tests
already on main via #4881, document the tiers across Rust, Python, Node
and the search guide, extend the remote request matrix to cover `0.1`
and `0.25`, and align the Python test package with beta.11.

`0.1` and `0.25` target empirical mean partition-routing recall of 80%
and 90% for L2, cosine and dot through `k=100000`. These are not
per-query or final Recall@k guarantees. Default Auto is unchanged;
Hamming and larger `k` remain uncalibrated, and remote queries require
corresponding server support. This PR makes no additional performance
claim. See [Lance
#10695](https://github.com/lance-format/lance/pull/10695) for
measurements and limitations.

Validation: both strict workspace Clippy configurations, Rust
formatting, 13 Rust effort tests, 208 Python query tests, 41 Node query
tests, native binding builds, TypeScript, Node lint/generated docs,
Python lint/format, full lockfile check and two dependency guards passed
on `a8b09170`. All validated Rust/Python/Node source and dependency
files are byte-identical at `2a82d07c`; the only subsequent change
restores the Java POM to main. Root Ruff has 59 existing diagnostics and
six formatting files, all byte-identical to the base; the Python package
passes.

The Java REST/Namespace client has no changed API here, and its
dependency remains identical to main. The separate [Java beta
publication failure](https://github.com/lance-format/lance/issues/10773)
is not claimed resolved or validated. Official SDK release, automatic
mirror, Sophon adoption and measured consumer acceptance remain
follow-up stages.
