v0.3.0

Breaking Changes

1. Improved content fetch interface ergonomics (commit 7b92405):
   • Replaced lexical::Analyzer::content() and Parser::content() methods that returned Result with a three-method approach:
     1. fn content(&self) -> Content - panics on error token
     2. fn err(&self) -> Error - panics on non-error token
     3. fn try_content(&self) -> Result<Content, Error> - original behavior
   • This eliminates the need for unwieldy .unwrap() and .unwrap_err() calls in parsing loops
2. Renamed BufAnalyzer to FixedAnalyzer (commit f8d9891):
   • Renamed the main lexical analyzer type to better reflect its purpose (analyzing fixed-size buffers)
   • Reduces confusion with the crate name and provides more descriptive naming
3. Improved Content::unescaped ergonomics (commit 0c33fcb):
   • Changed Content::unescaped method signature from &mut self -> &str to &mut self -> Cow<'_, str>
   • Returns Cow::Borrowed when no unescaping is needed, Cow::Owned when it expanded at least one escape sequence.

Material Non-Breaking Changes

1. Reduced fixed::Content (formerly buf::Content) size from 48 to 32 bytes (commit 0c33fcb)
2. Added Pos::new() constructor (commit 4f0527b):
   • Added convenience constructor for creating Pos instances: Pos::new(offset, line, col)
   • Improves testing ergonomics because it's a shorter "phrase"
3. Made Token::static_content() a const fn (commit 0cf5efb):
4. Added module-level documentation for mod lexical (commit 48e1025):
5. Switched from MIT license to dual MIT and Apache-2.0 (commit ad3f963):
6. Updated README (commits 4b09f21, 746e335, 0bd677f):
