tantivyr 0.1.3

Updated the bundled 'Tantivy' engine to 0.27.0 and refreshed the vendored 'Rust' crates. The on-disk index format is unchanged (v7), so existing indexes keep working. This also replaces the lru crate with a version that fixes RUSTSEC-2026-0253 (the unsound code was never reachable from 'tantivyr').
Fixed the macOS linker warnings reported by CRAN's M1mac additional checks ("object file was built for newer 'macOS' version than being linked"): on macOS the Cargo build now pins MACOSX_DEPLOYMENT_TARGET to rustc's own default for the platform (11.0 on Apple silicon) unless it is already set, so the C sources compiled by Cargo carry a minimum version that is never newer than the one R links against.

New fold_accents argument in tnt_text() and tnt_index_df(): removes diacritics from indexed words and queries (ASCII folding), so a query typed without accents, such as "orcamento", finds "orçamento". Stored text and snippets keep their accents.
New pt_news dataset: 36 short, fictional news stories in Brazilian Portuguese for trying out stemming, stop words, filters and highlights.
New vignette "Searching Portuguese text" covering stemming, stop words, accents and the query syntax.
Updated the bundled 'Tantivy' engine to 0.26.2 (bug-fix release; no API changes) and refreshed the vendored 'Rust' crates.
SystemRequirements now states the minimum supported 'Rust' version (rustc >= 1.88), so an outdated toolchain is reported clearly at configure time instead of failing during compilation.
Corrected the example return value in the tantivy_version() documentation.

Initial release.
tnt_index_df() indexes a data frame in one call (auto-schema).
Explicit schema API: tnt_schema() with tnt_text(), tnt_i64(), tnt_u64(), tnt_f64(), tnt_bool(), tnt_date() and tnt_json().
tnt_index() creates or opens on-disk and in-memory indexes.
tnt_add(), tnt_commit(), tnt_delete() and tnt_update() provide incremental updates.
tnt_search() returns a tibble with BM25 scores, structured filters (comparison expressions or Tantivy query strings), snippet highlighting and fast-field ordering; tnt_count() returns total match counts.
Portuguese and English stemming and stop words, plus other Snowball languages.
