fix(scripts): silence pnpm DEP0169 at provisioning install call sites (#12228)

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Worktree provisioning prepares the dependencies and tools that these
agents need.
> - The pinned pnpm version calls the deprecated `url.parse()` function
during each install.
> - Node.js 24 reports this call as `DeprecationWarning [DEP0169]`.
> - The provisioning scripts run more than one install, so the warning
repeats in each run.
> - This pull request disables only `DEP0169` at each affected pnpm
install call site.
> - The benefit is a clear provisioning log while other deprecation
warnings remain visible.

## Linked Issues or Issue Description

**What happened?**

The worktree provisioning scripts printed `DeprecationWarning [DEP0169]`
during each pnpm install. The warning came from pnpm 9.15.4 and its
`toNerfDart` call to `url.parse()`.

**Expected behavior**

The provisioning scripts should hide this known warning from the pinned
pnpm version. They should keep other deprecation warnings visible.

**Steps to reproduce**

1. Use Node.js 24 with pnpm 9.15.4.
2. Run worktree provisioning with a base-workspace repair or dependency
install.
3. Observe the repeated `DeprecationWarning [DEP0169]` output.

**Paperclip version or commit**

Commit `5cd41b1a9996713efdfdc62373da8045664c7f30`.

**Deployment mode**

Built from source.

**Installation method**

Built from source with pnpm.

**Agent adapter(s) involved**

Not adapter-specific (core bug).

**Database mode**

Not database-related.

## What Changed

- Add `--disable-warning=DEP0169` to each affected pnpm install call
site.
- Append the flag to `NODE_OPTIONS` so the scripts keep existing values.
- Add comments that name the source of the warning and the removal
condition.
- Add a regression test for all affected scripts and warning codes.

## Verification

- `bash -n scripts/provision-worktree.sh` passes.
- `bash -n scripts/provision-worktree-runtime.sh` passes.
- `node --test scripts/__tests__/provision-worktree-self-heal.test.mjs`
passes with 15 tests.
- GitHub Actions must pass all required checks before merge.

## Risks

This change has low risk. It changes warning output only for `DEP0169`.
It does not overwrite existing `NODE_OPTIONS` values. Revert commit
`5cd41b1a9996713efdfdc62373da8045664c7f30` to restore the prior output.

## Model Used

OpenAI Codex, GPT-5. The model used tool calls and code execution. The
runtime did not expose a context-window value.
