Lex Christopherson c80d640d35 feat: vendor Pi source into workspace monorepo
Vendor all 4 Pi packages (tui, ai, agent-core, coding-agent) from
pi-mono v0.57.1 as @gsd/* workspace packages under packages/. This
replaces the compiled npm dependency (@mariozechner/pi-coding-agent)
and patch-package workflow, giving direct source access for
modifications.

- Copy Pi source from pi-mono v0.57.1 into packages/
- Create workspace package.json + tsconfig.json for each package
- Rename ~240 imports from @mariozechner/pi-* to @gsd/pi-*
- Apply existing patches as source edits (setModel persist, VT input)
- Remove @mariozechner/pi-coding-agent dep and patch-package
- Update build pipeline to build packages in dependency order
- Add pi-upstream git remote for future selective syncing
