Compute batching (#849)

### Compute Batch Submission
- Consolidate duplicated action submission logic in `httpcomputeservice` into a single `HandleSubmitAction` supporting both single-action and batch (actions array) payloads
- Group actions by queue in `RemoteHttpRunner` and submit as batches with configurable chunk size, falling back to individual submission on failure
- Extract shared helpers: `MakeErrorResult`, `ValidateQueueForEnqueue`, `ActivateActionInQueue`, `RemoveActionFromActiveMaps`

### Retracted Action State
- Add `Retracted` state to `RunnerAction` for retry-free rescheduling — an explicit request to pull an action back and reschedule it on a different runner without incrementing `RetryCount`
- Implement idempotent `RetractAction()` on `RunnerAction` and `ComputeServiceSession`
- Add `POST jobs/{lsn}/retract` and `queues/{queueref}/jobs/{lsn}/retract` HTTP endpoints
- Add state machine documentation and per-state comments to `RunnerAction`

### Compute Race Fixes
- Fix race in `HandleActionUpdates` where actions enqueued between session abandon and scheduler tick were never abandoned, causing `GetActionResult` to return 202 indefinitely
- Fix queue `ActiveCount` race where `NotifyQueueActionComplete` was called after releasing `m_ResultsLock`, allowing callers to observe stale counters immediately after `GetActionResult` returned OK

### Logging Optimization and ANSI improvements
- Improve `AnsiColorStdoutSink` write efficiency — single write call, dirty-flag flush, `RwLock` instead of `std::mutex`
- Move ANSI color emission from sink into formatters via `Formatter::SetColorEnabled()`; remove `ColorRangeStart`/`End` from `LogMessage`
- Extract color helpers (`AnsiColorForLevel`, `StripAnsiSgrSequences`) into `helpers.h`
- Strip upstream ANSI SGR escapes in non-color output mode. This enables colour in log messages without polluting log files with ANSI control sequences
- Move `RotatingFileSink`, `JsonFormatter`, and `FullFormatter` from header-only to pimpl with `.cpp` files

### CLI / Exec Refactoring
- Extract `ExecSessionRunner` class from ~920-line `ExecUsingSession` into focused methods and a `ExecSessionConfig` struct
- Replace monolithic `ExecCommand` with subcommand-based architecture (`http`, `inproc`, `beacon`, `dump`, `buildlog`)
- Allow parent options to appear after subcommand name by parsing subcommand args permissively and forwarding unmatched tokens to the parent parser

### Testing Improvements
- Fix `--test-suite` filter being ignored due to accumulation with default wildcard filter
- Add test suite banners to test listener output
- Made `function.session.abandon_pending` test more robust

### Startup / Reliability Fixes
- Fix silent exit when a second zenserver instance detects a port conflict — use `ZEN_CONSOLE_*` for log calls that precede `InitializeLogging()`
- Fix two potential SIGSEGV paths during early startup: guard `sentry_options_new()` returning nullptr, and throw on `ZenServerState::Register()` returning nullptr instead of dereferencing
- Fail on unrecognized zenserver `--mode` instead of silently defaulting to store

### Other
- Show host details (hostname, platform, CPU count, memory) when discovering new compute workers
- Move frontend `html.zip` from source tree into build directory
- Add format specifications for Compact Binary and Compressed Buffer wire formats
- Add `WriteCompactBinaryObject` to zencore
- Extended `ConsoleTui` with additional functionality
- Add `--vscode` option to `xmake sln` for clangd / `compile_commands.json` support
- Disable compute/horde/nomad in release builds (not yet production-ready)
- Disable unintended `ASIO_HAS_IO_URING` enablement
- Fix crashpad patch missing leading whitespace
- Clean up code triggering gcc false positives
