fix: resolve remaining import.meta.url paths broken by airgap bundling

[DeDuva]

Summary

Follow-up to #23. A reviewer subagent audit of the M1+M2 replay flagged 5 more spots using the same import.meta.url-relative-offset pattern that breaks once squad-sdk's source is esbuild-bundled into squad-cli's single-file dist/squad.js:

• packages/squad-cli/src/cli/commands/loop.ts — generateLoopFile() (squad loop --init)
• packages/squad-cli/src/cli/commands/rc.ts and start.ts — remote-ui static asset serving (squad rc / squad start)
• packages/squad-sdk/src/sharing/consult.ts — getSquadAgentTemplatePath()
• packages/squad-sdk/src/presets/index.ts — getBuiltinPresetsDir(), which had no bundled fallback at all — squad-cli's built package never shipped the built-in presets directory in the first place. Added a postbuild step (packages/squad-cli/package.json) that copies squad-sdk's dist/presets/builtin into squad-cli/dist/presets/builtin.

All fixes follow the same shape as #23: try both the unbundled offset and the bundled (sibling-of-dist) offset, use whichever exists. rc.ts/start.ts share a new resolveRemoteUiDir() helper since they had identical logic.

Test plan

• Rebuilt (npm run build) and confirmed dist/presets/builtin is now populated in the shipped bundle (previously empty/absent)
• Manual repro via the bundled CLI: squad loop --init in a fresh scratch repo — creates loop.md with real template content (previously would have silently resolved to the wrong/stale path)
• npx vitest run test/remote-control.test.ts test/presets.test.ts test/init-sdk.test.ts test/sdk-templates-dir-resolution.test.ts — 152/152 passing
• npm run lint (typecheck both packages) — clean
