The {{#if contextFiles.length}} block (line 10) was never closed with
{{/if}}, causing Handlebars to throw 'if doesn't match ifAny' at
runtime when the template is compiled.
Additionally, the git version control section (git.isRepo guard with
branch, status, and commit history) was missing entirely, even though
the outer {{#ifAny contextFiles.length git.isRepo}} guard references it.
This fix:
- Adds the missing {{/if}} to close the contextFiles.length block
- Restores the git.isRepo conditional section for version control info
- Ensures </project> and {{/ifAny}} are properly positioned

- Renamed `job_ids` parameter to `jobs` in await tool schema.
- Removed `timedOut` field from await tool result details.

- Restructured task tool documentation for clarity, moving parameter definitions into a dedicated section and consolidating guidance on context, assignments, and parallelization.
- Reformatted system prompt template to use markdown headings instead of XML tags for skills, preloaded skills, and rules sections.

DIFF_PLUS_RE matched both '+' and '-' (unified-diff markers), but '-'
is also a valid Markdown/YAML list prefix. When all replacement lines
start with '- ', the 50%-threshold heuristic in stripNewLinePrefixes
fires and strips every leading '-', corrupting list-item content.
Narrow the regex to match only '+' (added-line markers), which is the
stated intent of the docstring and the safe strip target. Removed
lines ('-') are never valid replacement content in any case.
Reproducer: passing content=["- [x] item"] as a bare string to a
set/replace op — the '-' is silently dropped, writing ' [x] item'.
Passing content as string[] bypasses stripNewLinePrefixes entirely and
was the workaround, but the root cause should be fixed.
