feat: Add benchmarking harness with spot suite (#10)

* feat: Add benchmarking harness for agent evaluation

Introduces ironclaw-bench, a Rust-native benchmarking crate that drives the
real agent loop headlessly. Supports standard benchmarks (GAIA, Tau-bench,
SWE-bench Pro) and custom JSONL task sets with parallel execution, resume
support, and incremental JSONL output.

Key components:
- BenchChannel: headless Channel impl with auto-approval and response capture
- InstrumentedLlm: LlmProvider wrapper recording per-call token/cost metrics
- BenchRunner: task orchestration with parallel execution and JSONL resume
- Scoring utilities: exact match, contains, regex (all with normalization)
- CLI: run, results, compare, list subcommands via clap
- Four suite adapters: custom, gaia, tau_bench, swe_bench

Also fixes a pre-existing missing SseEvent::ToolResult match arm in the web
gateway and adds FinishReason to the LLM module's public re-exports.

* feat: Add spot benchmark suite for end-to-end agent verification

Adds a "spot" suite with 13 scenarios across 4 categories (smoke,
tool use, multi-tool chaining, robustness) using multi-criterion
assertions instead of simple text matching. Also adds an `error`
field to TaskSubmission so suites can hard-fail on agent errors.

* fix: address audit findings in benchmarks crate

- Fix O(n²) scoring loop by indexing tasks in a HashMap (was re-parsing JSONL per result)
- Add UTF-8-safe truncation to prevent panic on multi-byte chars in channel capture
- Wire setup_task/teardown_task into both sequential and parallel runner paths
- Convert BenchRunner.suite from Box to Arc for parallel task setup/teardown
- Add tracing::warn for placeholder scores in custom, swe_bench, tau_bench adapters
- Add spot suite to CLI help text
- Add doc comment clarifying tools_used HashSet behavior in SpotAssertions
- Reorder match arms in create_suite to match KNOWN_SUITES alphabetical order

* fix: rewrite tasks.jsonl with scored results after scoring

The JSONL file was only written during execution (pre-scoring), so the
`results` command showed "pending" scores even after scoring completed.
Now the runner rewrites the JSONL with final scored results, keeping
task-level and aggregate data consistent.

* feat: prefix benchmark runs with model name and commit hash

Run logs and results table now show the base model and short git commit
hash, making it easy to correlate results with code versions. The commit
hash is also persisted in run.json for historical tracking.

* feat: add 8 memory benchmark scenarios to spot suite

Tests save-and-recall workflows using file tools:
- daily tasks, reminders, meeting notes, append logs
- detail extraction, todo priorities, multi-file ops
- context updates (write-read-rewrite-verify)

Total spot scenarios: 13 -> 21

* chore: fmt channel.rs and gitignore bench-results

Co-Authored-By: Claude Opus 4.6 <[email protected]>

* fix: address critical and high findings from PR review

- Fix race condition: parallel mode now writes JSONL after all tasks
  complete instead of concurrent unsynchronized appends
- Fix UTF-8 panic: use .chars().take(25) instead of byte slicing on
  task_id which could panic on multi-byte characters
- Remove dead code: max_iterations (parsed but never used),
  tool_whitelist() (declared but never called), MatrixEntry.tools
  (declared but never applied)
- Eliminate double load_tasks(): cache task list on first load and
  reuse the index for scoring instead of re-reading from disk

* fix: relax smoke-greeting assertion to not demand parrot greeting

The LLM often introduces itself without echoing "hello" back. Use a
regex that accepts any reasonable self-introduction (hello, hi, hey,
assistant, agent, help) instead of demanding a specific word.

Co-Authored-By: Claude Opus 4.6 <[email protected]>

* feat: 100% spot baseline (GPT-5.2 @ 2c43b83, 21/21 pass)

Relax two brittle assertions:
- smoke-greeting: use regex for any reasonable self-intro instead of
  demanding the model parrot "hello"
- memory-update-context: drop response_not_contains PST since the
  model correctly says "not PST" which triggers the literal check
- memory-multifile: lower min_tool_calls from 4 to 3, the model can
  batch two writes in one LLM turn

Baseline results committed to benchmarks/baselines/ for regression
tracking. Local runs stay in bench-results/ (gitignored).

Results: 100.0% pass, 1.000 avg, $0.31 cost, 111s wall time

* fix: address remaining PR review comments

- Replace .expect("semaphore closed") with proper error handling
- Derive PartialEq on BenchScore for cleaner test assertions
- Use ToPrimitive::to_f64() instead of string roundtrip in estimated_cost()
- Validate SWE-bench inputs: task_id (path traversal), repo (owner/repo format),
  base_commit (valid git ref) with 5 new tests
- Skip "pending" (unscored) entries during resume so they get re-executed
- Use run.json mtime for find_latest_run (falls back to tasks.jsonl, then dir)
- Move additional_tools() outside parallel loop to share Arc<[Tool]> across tasks
- Add doc comments documenting known limitations (single-turn, resources, conversation)

* fix: reject absolute paths in SWE-bench and validate matrix config

- is_safe_path_component now rejects paths starting with '/'
- BenchConfig::from_file validates matrix is non-empty
- Added tests for both validations

Co-Authored-By: Claude Opus 4.6 <[email protected]>

* fix: fail tasks on setup_task error and compute git hash once

- setup_task failure now records an error TaskResult instead of
  continuing to run the task (both sequential and parallel paths)
- git_short_hash() computed once per run instead of twice
