chore: weekly merge of branch lockfiles into main

[yomybaby]

Summary

Weekly merge of stale branch-named pnpm lockfiles into pnpm-lock.yaml.

Same chore as precedent commit ebc0b2a43. All deleted lockfiles correspond to PRs already merged into main:

• pnpm-lock.04-28-feat_fr-2762_*.yaml → feat(FR-2761): add deployment preset create/edit/delete UI #7125 (FR-2761/2762)
• pnpm-lock.04-30-fix_fr-2787_*.yaml → fix(FR-2787): deployment CRUD UI/UX improvements #7191 (FR-2787)
• pnpm-lock.05-07-fix_fr-2829_*.yaml → fix(FR-2829): move relay:watch to root and fix schema watch paths #7278 (FR-2829)
• pnpm-lock.refactor!fr-2529-*.yaml → refactor(FR-2529): extract backend.ai-client as standalone workspace package #6614 (FR-2529)
• pnpm-lock.claude!charming-austin.yaml → tied to FR-2529 work

How it was produced

```bash
rm node_modules/.pnpm-workspace-state-v1.json # bypass install-skip cache
pnpm install --merge-git-branch-lockfiles --config.minimumReleaseAge=0
```

The two flags are needed because (1) the workspace-state cache makes pnpm exit before the merge step runs, and (2) minimumReleaseAge: 10080 in pnpm-workspace.yaml blocks install on packages whose registry metadata lacks a time field.

Test plan

• pnpm install resolves with single pnpm-lock.yaml
• No active branches own the deleted lockfiles
