* code-testing-agent: add polyglot pipeline examples for Python/TypeScript/Go/Java
The code-testing-agent skill family is polyglot in description but in
practice biased toward .NET because dotnet-examples.md was the only
filled-in pipeline walkthrough. The four sub-agents that participate in
the Research-Plan-Implement pipeline (researcher, planner, implementer,
generator) all pointed to dotnet-examples.md whenever they suggested a
concrete example, which made it harder for the agent to produce
idiomatic non-.NET tests (e.g. in msbench top5-* benchmarks for
Python/Flask, TypeScript/Express).
This change
* adds four new example files mirroring dotnet-examples.md format
(source → research → plan → generated test → fix cycle → final report):
- python-examples.md (pytest, unittest.mock, Mock(spec=...), parametrize)
- typescript-examples.md (Vitest with notes for Jest; it.each,
async tests, fake timers, ESM/CJS fix cycle)
- go-examples.md (standard testing package, table-driven subtests,
hand-written fake repository, injected clock)
- java-examples.md (JUnit 5 + Mockito on Maven, @ParameterizedTest +
@CsvSource, Clock.fixed, Surefire fix cycles)
* updates code-testing-extensions/SKILL.md TOC to list the new files
and clarifies usage instructions to read the matching <language>-
examples.md alongside the base extension
* makes the "Concrete example" pointers in code-testing-generator,
code-testing-implementer, code-testing-planner and
code-testing-researcher agents language-agnostic (list all available
example files instead of hard-coding dotnet-examples.md)
* expands code-testing-researcher project-structure detection list to
cover more Python (tox.ini, noxfile.py, requirements*.txt, uv.lock,
poetry.lock, pdm.lock), JS/TS (.mts/.cts/.jsx, vitest.config.*,
jest.config.*), C++ (CMakeLists.txt, BUILD.bazel, meson.build),
Java/Kotlin (pom.xml, build.gradle[.kts], wrappers), and other
ecosystem files; expands the Identify-Language section accordingly
* extends the "Language-Specific Examples" section in
code-testing-agent/SKILL.md to summarise each example file

* Address review feedback for #708
- go-examples.md: replace the hand-rolled `contains`/`stringIndex`
helpers with `strings.Contains` from the standard library. The hand-rolled
`contains` had subtly wrong semantics — `contains(""abc"", """")` returned
`false` while `strings.Contains` returns `true` — and the helpers are
unnecessary complexity for a code-generation example.
- go-examples.md: in the `go test -run` "wrong selection regex" sample fix
cycle, quote the test name and use `single_item` (matching the underscore
that the surrounding diagnosis text refers to) instead of the unquoted
`single item` which the shell would parse as two separate CLI arguments.
- java-examples.md: the source-tree file list described `Invoice.java` as a
`record` but the `InvoiceService.markAsPaid` example mutates the invoice
via `setStatus(...)` and `setPaidDate(...)` — records are immutable, so
the description was internally inconsistent. Re-describe it as a mutable
POJO with explicit mutators to match the service code.

Add end-to-end input/output examples to anchor expected behavior for the
LLM, addressing the Example Quality (2/5) review feedback.
Changes:
- New extensions/dotnet-examples.md with .NET-specific examples: sample
source code, research output, plan output, generated test file, fix
cycle walkthroughs, and final report
- SKILL.md: replace one-liner examples with strategy selection table,
pipeline walkthrough, and pointer to language-specific extensions
- Generator agent: add strategy decision examples and sample final report
- Researcher/Planner/Implementer agents: add references to extension
examples for concrete output shapes
Architecture keeps core agents language-agnostic — all language-specific
examples live in the extensions/ folder.
- Add 'Use when:' trigger phrases to all 7 sub-agent descriptions
so parent agents can reliably discover and delegate to them
- Add .testagent/ cleanup rule to generator agent to prevent
ephemeral pipeline state from being committed
