fix: prevent LaTeX parsing inside link text

Fixes #206

## Problem

When parsing links with dollar signs in the text, like:
`[$NVIM_APPNAME](https://example.com/$VAR)`

The parser incorrectly interpreted `$` inside link text as the start of
a LaTeX block, preventing the link from being parsed correctly.

## Root Cause

The `_inline_base` grammar rule included `$.latex_block`, which was used
in ALL inline contexts including inside link text (`_inline_element_no_link`).

## Solution

Created a new `_inline_base_no_latex` rule that excludes LaTeX blocks, and
modified the dynamic rule generation to use this variant when generating
`_inline_element_no_link` rules (used inside link text).

**Changes:**
- Added `_inline_base_no_latex` rule without `$.latex_block`
- Modified line 401 to use appropriate base rule based on context:
  - Inside links (`link=false`): Use `_inline_base_no_latex`
  - Outside links (`link=true`): Use `_inline_base` (with LaTeX)

## Testing

✅ All existing tests pass
✅ Links with `$` characters now parse correctly
✅ LaTeX still works outside of link text

## Additional Changes

Upgraded to tree-sitter 0.25 to match latest ABI (same as #207):
- Updated Cargo.toml dependencies
- Updated parser.rs API calls
