The lower parameter was a footgun: callers had to keep it in sync with the
loop bound over text. Instead, skipXMLIgnoredSection now accepts only text
and constructs strings.ToLower(tail) internally for its prefix checks.
This eliminates the entire class of len(text) vs len(lower) boundary bugs
along with the min() workaround.
Also changes:
- findToolCDATAEnd: drop lower param, use text directly for closeMarker
search (]]> is ASCII, ToLower is a no-op for it)
- cdataEndLooksStructural: drop lower param, use raw text byte comparison
- All external callers: loop bound reverts to plain len(text)
The inner tag-matching functions (findXMLStartTagOutsideCDATA,
findMatchingXMLEndTagOutsideCDATA) retain their own local lower for
HasPrefix comparisons against the target tag name, keeping concerns
properly separated.
Fixes#435.
Support `<dsml_tool_calls>`, `<dsml_invoke>`, `<dsml_parameter>` in
addition to the existing pipe, space, hyphen, and collapsed forms.

Add compatibility for <dsml-tool-calls>/<dsml-invoke>/<dsml-parameter>
tag forms alongside the canonical pipe-prefixed DSML shell. Hyphenated
forms only activate when a DSML prefix is detected, preventing false
matches on bare XML lookalikes. Go and Node parsers aligned, with tests
covering here-doc CDATA, streaming sieve, and negative lookalike cases.

Replace hardcoded DSML typo variant lists in Go/Node tool call parsers with
generalized prefix consumption that tolerates repeated leading <, repeated DSML
prefix noise, and trailing pipe terminators. Split tiktoken-dependent token
counting into a build-tagged file for non-cgo platform compatibility. Add /data
directory to Dockerfile for bind-mount permissions.

- Add shared ToolMarkupTag scanner (toolcalls_scan.go) replacing hardcoded alias tables
- Support DSML collapsed tag names (<DSMLtool_calls>, <DSMLinvoke>, <DSMLparameter>)
- Parse JSON literal values from parameter bodies (123→number, true→bool, null)
- Recover unclosed CDATA in final parse/flush via SanitizeLooseCDATA
- Align Go and Node implementations (scanToolMarkupTagAt, findMatchingToolMarkupClose)
- Reject bare <invoke> as unsupported syntax, only tool_calls wrapper triggers tool path
- Update API.md and toolcall-semantics.md documentation

- Guard current_input_file.enabled / thinking_injection.{enabled,prompt} with hasNestedSettingsKey so partial updates don't overwrite omitted fields
- Expand DSML alias support to tolerate space-separated tags (e.g. <|dsml invoke>) alongside pipe-separated forms
- Sync Go sieve, Node sieve, toolcall parser, and tests for all new DSML variants
- Update API.md and toolcall-semantics.md with expanded alias coverage

Add support for DSML wrapper aliases (<dsml|tool_calls>, <|tool_calls>,
<｜tool_calls>) alongside canonical XML. Normalize mixed DSML/canonical
tags instead of rejecting them. Add tilde fence (~~~) support, fix
nested fence and unclosed fence handling, support CDATA-protected fence
content, and skip prose mentions when scanning for real tool blocks.
Mirror all changes between Go and Node.js runtimes.
