fix(typecheck): make bun run typecheck actionable on main (#473 )

Issue #473 reported that `bun run typecheck` fails on main with ~4400 errors due to repo-foundation drift, masking branch-specific regressions. Per kevincodex1's guidance ("lets narrow the typecheck scope for now and then we expand step by step") this PR addresses the foundational root causes and brings the error count down 60% so the gate is actionable for branch reviews. Changes: - tsconfig.json: bump target to ES2023 + add lib ["ES2023", "DOM"] so Array.findLast / findLastIndex resolve (kills 41 TS2550 errors). Add `noEmit: true` for typecheck-only mode and `allowImportingTsExtensions: true` (kills 40 TS5097 errors). Set `noImplicitAny: false` because cleaning up TSX-component implicit any is explicitly out of scope per the issue. - src/global.d.ts: ambient declaration for the build-time MACRO global injected by scripts/build.ts via Bun's `define` option (kills 9 TS2304 'Cannot find name MACRO' errors). - src/types/{message,utils,tools}.ts: stubs for the highest-impact missing modules from the partial source snapshot (~21 importers for message alone). Document the snapshot caveat at the top of each stub and reference issue #473 so future readers know they're placeholders. - src/entrypoints/sdk/controlTypes.ts and src/constants/querySource.ts: similar one-file stubs unblocking 18 + 19 importers respectively. - src/entrypoints/agentSdkTypes.ts: append `any`-typed aliases for ~70 SDK names that callers expect on the public surface but that live in stubbed sub-files (PermissionMode, SDKCompactBoundaryMessage, HookEvent, ModelUsage, ModelInfo, etc. — exactly the list from auriti's bug-report enumeration). Verified locally on Linux: - baseline `bunx tsc --noEmit` on stashed main: 4434 errors - with PR applied: 1782 errors (60% drop) - `bun run build`: passes (v0.7.0) - `bun test`: 1632 pass; the 4 remaining failures (StartupScreen, thinking) reproduce on main and are unrelated. - TS2550 (lib): 41 → 0 - TS5097 (.ts imports): 40 → 0 - TS2304 'MACRO': 9 → 0 - TS2307 missing modules: 587 → 325 Remaining errors are localized to specific stubbed modules and can be addressed in smaller follow-up issues, matching the issue's "Definition of done" criterion.
