releases/rust/v0.25.0

Added

• Writer::add_schema_with_id and Writer::add_channel_with_id for writing records with explicit IDs without content de-duplication, so distinct IDs from a source file are preserved even when content is identical (#1632).
• Public mcap::VERSION and mcap::LIBRARY_IDENTIFIER constants (#1702).
• WriteOptions::DEFAULT_CHUNK_SIZE constant.

Changed

• Default writer Header.library string is now mcap-rust/<version> (was mcap-rs-<version>) (#1702). Breaking for anyone asserting on the exact string.
• Default chunk size increased to 1 MiB (was 768 KiB), standardizing with the other MCAP libraries (#1659).
• Established a minimum supported Rust version (rust-version = "1.81") (#1710).
• Dependency bumps: binrw 0.12 → 0.15, thiserror 1 → 2 (#1705, #1710).

Removed

• Removed unused McapError variants AttachmentInProgress, RecordTooShort, and UnexpectedChunkRecord (#1494). Breaking for code matching on these variants.

Fixed

• Corrected typos in several McapError messages (e.g. expeted → expected, mulitple → multiple) — note these are user-visible error string changes (#1492).
• Fixed typos and inaccurate references in doc comments, including ChunkIndex::compressed_data_offset now correctly documenting BadChunkStartOffset (#1607, #1516).
