Some refactoring, renaming, and debug assertions for clarity and safety
...
- Add more `assume()` checks in the lexer
- Replace double negative "`disable* = false`" with "`enable* = true`"
- Naming convention of "`std::deque<> *Stack`" when relying on
`.push_front()` and `.pop_back()`

Consolidate, refactor, and bugfix the lexer's handling of captures and skips ( #1957 )
...
- Do not error about local labels following keywords in skips or captures (fixes #1955 )
- Do not incompletely attempt to handle line continuations in skips (fixes #1956 )
- Rename `skipToLeadingIdentifier` to `skipToLeadingKeyword`, refactor to merge
`skipToEOL` into it, and use it for both skips and captures

Fix some fixed-point literal lexing issues ( #1914 )
...
- No fractional digits are necessary after the decimal point,
e.g. `42.` is valid instead of `42.0`
- Error messages refer to "fixed-point" not "integer" constants
- Test more carefully for lexing unrelated to underscores

Use loops instead of tail calls and musttail
...
gcc 15.2.1 20250813 complains "address of automatic variable can
escape to `musttail` call" from `-Wmaybe-musttail-local-addr`,
and guaranteeing tail-call optimization cross-platform is more
trouble than it's worth.
