fix(claude-local): tolerate sandboxes whose Claude CLI lacks --effort (#8393)

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The claude-local adapter launches the Claude CLI inside execution
environments (local, SSH, and ephemeral sandboxes such as Daytona)
> - Newer adapter code passes `--effort` to the CLI, but the Claude
binary baked into some sandbox images is older and rejects it with
`error: unknown option '--effort'`, so every run in those environments
fails
> - This needs addressing because the failure is environment-dependent
and silent from the operator's perspective — the run just dies with a
CLI usage error
> - This pull request probes the in-sandbox CLI for `--effort` support
once, caches the result per environment, and strips the flag (with a
warning) when the CLI does not support it
> - The benefit is that sandboxes with older Claude CLIs keep working
instead of failing, with negligible probe overhead because the
capability check is cached and reused across ephemeral leases

## Linked Issues or Issue Description

No public GitHub issue exists. Describing the bug inline following the
bug report template:

### What happened?

Runs using the `claude-local` adapter inside certain sandbox/execution
environments fail with `error: unknown option '--effort'`. The adapter
unconditionally appends `--effort` to the Claude CLI invocation, but the
Claude CLI version present in some sandbox base images predates that
flag, so the process exits with a usage error and the run dies.

### Expected behavior

The adapter should detect that the target environment's Claude CLI does
not support `--effort` and degrade gracefully — drop the flag and emit a
warning — rather than failing the run.

### Steps to reproduce

1. Configure an execution environment (e.g. a sandbox image) whose
bundled Claude CLI is old enough to predate the `--effort` option.
2. Run any claude-local task that resolves to an effort level (so
`--effort` is appended).
3. Observe the run fail immediately with `error: unknown option
'--effort'`.

### Paperclip version or commit

`master` at the time of this PR (branch forked from current `master`).

### Deployment mode

Self-hosted / local instance using execution environments (reproducible
with ephemeral sandbox providers such as Daytona where `reuseLease:
false`).

### Agent adapter(s) involved

Claude Code (`claude-local`).

## What Changed

- Add a CLI capability probe (`cli-capabilities.ts`) that runs the
target Claude binary's `--help` inside the execution environment to
detect `--effort` support.
- Strip `--effort` from the CLI args (emitting a warning) when the probe
reports the flag is unsupported; keep it otherwise.
- Cache probe results keyed by
`sandbox:providerKey:environmentId:command` (no lease id) so the probe
is reused across ephemeral leases — important for `reuseLease: false`
sandbox configs like Daytona, which would otherwise re-probe on every
run.
- Conservative fallback: if the probe itself can't run/parse, assume the
flag is supported (preserves prior behavior).

## Verification

- `node_modules/.bin/vitest run
src/__tests__/claude-local-execute.test.ts
src/__tests__/claude-local-adapter-environment.test.ts` → **2 files, 30
tests passed**.
- Regression test issues two `execute()` calls with distinct lease ids
and asserts the in-sandbox `--help` probe runs exactly once (cache reuse
across leases).
- Added tests covering: flag stripped when unsupported, flag retained
when supported, warning emitted, and conservative fallback when the
probe fails.

## Risks

Low risk. The change is additive and gated behind a probe with a
conservative default (assume supported on probe failure), so existing
environments that support `--effort` are unaffected. Worst case for an
environment where the probe is unreliable is the prior behavior (flag
passed through).

## Model Used

Claude Opus 4.8 (claude-opus-4-8), extended thinking, with tool use /
code execution via Claude Code.
