feat(config-schema): mirror experimental swe_pruner keys from CLI config

[Drilmo]

Summary

Mirrors two new experimental CLI config keys in the config JSON Schema overlay, per the sync convention documented at the top of apps/web/src/app/config.json/extras.ts:

• experimental.swe_pruner (boolean) — enables SWE-Pruner, task-aware pruning of large read/grep tool outputs
• experimental.swe_pruner_model (string) — optional provider/model override for the skimming model

Both keys are added in Kilo-Org/kilocode#11980 (marked kilocode_change in packages/opencode/src/config/config.ts). Without this mirror, users with $schema: https://app.kilo.ai/config.json get "unknown property" warnings when setting these keys. Descriptions are copied verbatim from the zod schema, and the matching assertions were added to apps/web/src/tests/cli-config-schema.test.ts (step 4 of the documented procedure).

Verification

• No manual testing performed: the change is two schema literal entries plus two test assertions following the exact pattern of the adjacent codebase_search / native_notebook_tools entries. The local environment lacks Node >=24 required by this repo's engines field, so pnpm test / pnpm format could not be run locally — relying on CI for the jest suite and format check. The edits copy the existing file style (quotes, indentation, trailing commas) so oxfmt should be a no-op.

Reviewer Notes

Companion to Kilo-Org/kilocode#11980 — best merged once that PR lands (the keys are harmless in the schema overlay before then; the CLI simply ignores unknown experimental keys). Note that sandbox / sandbox_restrict_network / speech_to_text_model from the same kilocode_change experimental block are currently absent from this overlay too; left untouched here to keep this PR scoped, but may be worth a follow-up sweep.

Executive Summary

Mechanical schema mirror adding two experimental config keys (swe_pruner, swe_pruner_model) that exactly follows the file's existing pattern, with matching test assertions; no bugs or security concerns found in the changed lines.

@Drilmo right now the swe_pruner doesn't perform very well cost wise on our internal evals. I am actively researching why, but until then we should put any further changes on hold.

[marius-kilocode]

Let's merge this anyway already, since it's already in the client.
