feat(cpp): add CMake, CTest, Make, Ninja, and MSBuild handlers

[isink17]

Summary

Adds focused, token-efficient output handlers and safe automatic rewrites for common C++ build and test workflows:

• CMake configure and build
• CTest
• Make
• Ninja
• MSBuild

The handlers preserve the original executable arguments, targets, configuration, platform, environment, working directory, and native exit code while reducing progress and build noise.

Correctness and failure handling

• Non-zero exits cannot produce a success summary.
• Unknown or empty failures emit an explicit <tool>: failed (exit N) result.
• Raw failure fallback is bounded to 40 total lines and 4096 characters.
• The runner behavior is opt-in through RunOptions::preserve_filtered_failure_output; existing callers and default never_worse behavior remain unchanged.
• MSBuild /t:Link remains /t:Link; no build target is changed.

Supported diagnostics

• GCC and Clang compiler/linker diagnostics
• MSVC compiler diagnostics
• LINK/LNK and RC diagnostics
• multiline CMake errors
• Ninja FAILED: blocks and failure sentinels
• ordinary CTest failures, timeouts, crashes, exceptions, and sanitizer output
• MSBuild compiler, linker, RC, MSB, PRJ, and CVT diagnostics

Rewrite safety

Automatic rewriting is limited to normal build and test invocations.

Native output is preserved for informational, query, structured-output, dry-run, debug, and tool modes, including:

• CMake help/version/script/tool/install/workflow modes
• CTest listing and structured show-only modes
• Make dry-run, question, database, debug, trace, help, and version modes
• Ninja tool, dry-run, debug, verbose, help, and version modes
• MSBuild help, version, query, preprocess, and target-listing modes

Make lifecycle targets such as clean, install, and distclean remain native. Make option parsing handles clustered flags, options occurring after targets or assignments, option operands, and the -- boundary.

Command arguments and ordering are preserved.

Validation

• Runner tests: 7 passed
• C++ handler tests: 49 passed
• Registry tests: 375 passed
• cargo check --all-targets: passed
• cargo fmt --all -- --check: passed
• cargo clippy --all-targets: passed

The full branch suite completed with:

• 2612 unit tests passed
• 10 integration tests passed
• 8 tests ignored
• 1 existing upstream integration failure

Existing upstream failure:

grep_no_match_emits_empty_not_a_message

The same Some(2) versus Some(1) failure was reproduced on a detached clean upstream/develop worktree.

Scope

This PR intentionally excludes PowerShell rewriting, grep/JSON additions, codegraph handling, patch/encoding changes, Git normalization, and other unrelated features. Those will be handled separately.
