fix: resolve all open Dependabot security alerts

[mishushakov]

Fixes all 30 open alerts on https://github.com/e2b-dev/code-interpreter/security/dependabot

Pillow 12.2.0 → 12.3.0 (25 alerts, high/medium)

Bumped in all three manifests: template/requirements.txt, python/poetry.lock, chart_data_extractor/poetry.lock. Fixes heap out-of-bounds writes (ImageCmsTransform.apply(), Image.paste()/crop(), RankFilter), several decompression-bomb-check bypasses (font loading, GD images), OS command injection in WindowsViewer.get_command(), and multiple DoS issues. Includes a changeset for @e2b/code-interpreter-template.

npm transitive deps in pnpm-lock.yaml (5 alerts)

• js-yaml 3.14.2 → 3.15.0 and 4.1.1 → 4.3.0 — quadratic merge-key DoS (GHSA-52cp-r559-cp3m, GHSA-h67p-54hq-rp68)
• brace-expansion 1.1.14 → 1.1.16 — exponential-time expansion DoS (GHSA-3jxr-9vmj-r5cp)
• esbuild 0.27.x → 0.28.1 — dev-server file read on Windows (GHSA-g7r4-m6w7-qqqr, low). Both vite 7.3.5 and tsup 8.5.1 (latest) pin ^0.27.0, so this needs a pnpm.overrides entry in the root package.json.

Verification

• poetry lock diffs contain only the pillow version change (rest is wheel-hash churn)
• pnpm run build in js/ (tsc + tsup) succeeds with esbuild 0.28.1
• vitest boots and transforms all 31 test files with the overridden esbuild

PR Summary

Low Risk
Dependency-only security bumps with no application logic changes; esbuild override is dev-tooling scoped though it affects the whole pnpm tree.

Overview
Closes open Dependabot alerts by bumping Pillow from 12.2.0 to 12.3.0 in the code-interpreter template (template/requirements.txt) and both Poetry lockfiles (python/, chart_data_extractor/), with a patch changeset for @e2b/code-interpreter-template.

On the JS side, root pnpm.overrides forces esbuild to ≥0.28.1 (vite/tsup still pull 0.27.x), and pnpm-lock.yaml picks up patched transitive versions (js-yaml, brace-expansion, postcss). .tool-versions moves Poetry from 1.8.5 to 2.1.1, which also reformats the Poetry lock metadata.
