fix: add click to base install dependencies (#610)

## Summary

The `Test pip install (ubuntu-latest, 3.14, latest)` CI job has been
failing on `main` (e.g.
https://github.com/pasteurlabs/tesseract-core/actions/runs/26502477818/job/78046217060).
Two related issues, both exposed by newer `typer` / a base-only install:

### 1. `ModuleNotFoundError: No module named 'click'`

`tesseract_core/sdk/cli.py` does `import click` unconditionally and the
SDK CLI is exposed via `[project.scripts]`, so `click` must be in the
base install — not only in the `runtime` extra. Until now it was pulled
in as a transitive dependency of `typer`, but newer `typer` releases
(`>= 0.16` ish) no longer guarantee this, so `pip install
tesseract-core` with the latest dep set fails at CLI import.

### 2. `RuntimeError: Type not yet supported: <class
'click.core.Context'>` (then typeguard hit too)

Once `click` is installed, a second latent issue surfaces in
`cli.py:run_container`. It declared its context parameter as
`click.Context`, which fails at typer command registration on `typer >=
0.16`. Annotating as `typer.Context` (a thin subclass of
`click.Context`) gets past typer's resolver but then trips typeguard at
call time, because the context object click actually injects at runtime
is a plain `click.Context`, not an instance of the `typer.Context`
subclass:

```
typeguard.TypeCheckError: argument "context" (click.core.Context)
    is not an instance of typer.models.Context
```

The context was only used to invoke `context.get_help()` in two
branches. Drop the parameter entirely and look the context up via
`click.get_current_context()` at the point of use, which avoids both the
typer parameter-type check and the typeguard runtime check.

## Commits

1. fix: add `click` to base install dependencies` — declare `click` as a
real dependency. Pre-commit hooks regenerate `production.uv.lock` /
`requirements.txt`; lockfile churn is mostly cosmetic (the pinned `uv
0.6.11` in the hook re-serialises every entry).
2. fix: drop `click.Context` parameter from `run_container` — remove the
offending parameter from `run_container`'s signature; replace
`context.get_help()` with `click.get_current_context().get_help()` at
the two call sites.

## Test plan

- [x] `Test pip install (latest)` — should clear the
`ModuleNotFoundError`.
- [x] `tesseract --help` / `tesseract run --help` still work locally.
- [x] `tesseract run` (no args) still surfaces the same `BadParameter`
errors via typer's existing error rendering.
