chore(rebrand): rename workspace scope @t3tools/* → @bcode/* (#8)

* chore(rebrand): rename workspace package names @t3tools/* → @bcode/*

* chore(rebrand): update workspace dependency refs to @bcode/*

* chore(rebrand): point turbo filters at @bcode/* packages

* chore(rebrand): rewrite @t3tools/* imports and turbo refs to @bcode/*

* docs(rebrand): update package-scope references to @bcode/*

* chore(rebrand): regenerate bun.lock for @bcode/* workspace rename

* chore(rebrand): reformat imports after @bcode/* rename

* docs: apply PR review fixes + switch CI to github-hosted runner

- ci.yml: blacksmith-4vcpu-ubuntu-2404 → ubuntu-24.04 (fork
  can't claim a Blacksmith runner; all main runs since 01:04 UTC
  were stuck queued).
- .docs/provider-architecture.md: reflect Claude-first (default
  provider is claudeAgent, Codex is secondary) and drop the stale
  NativeApi-in-@bcode/contracts claim; point at the actual
  environmentApi.ts / localApi.ts consumers.
- docs/perf-benchmarks.md: "builds t3" → "builds @berkayorhan/bcode".
- AGENTS.md: drop duplicate legacy-dir bullet now covered by the
  "kept as-is" block above it.

+BCode is Claude-first. The default provider is `claudeAgent` (configured in `packages/contracts/src/orchestration.ts`); Codex is available as a secondary option via the provider picker.

 - **User-facing strings** (UI labels, dialog text, window titles, error messages, docs, release names): Use **"BCode"**. Never introduce new "T3 Code" references.
-- **Internal identifiers — do NOT rename** (upstream compatibility):
-  - Environment variables: `T3CODE_*` prefix
-  - Protocol scheme: `t3://`
-  - Home directory: `~/.t3`
-  - Package scopes: `@t3tools/*`
-  - npm package `t3`, `npx t3` commands
-  - COM identifiers: `com.t3tools.t3code`
-  - Linux desktop entries: `t3code.desktop`
-  - localStorage keys: `t3code:theme`
-  - TypeScript types, internal constants
-- **Legacy directory names** (e.g. `LEGACY_USER_DATA_DIR_NAME`): Keep as "T3 Code" — they reference old on-disk paths for migration.
+- **Internal identifiers — renamed in v0.0.19:**
+  - Environment variables: `T3CODE_*` → `BCODE_*` (`T3CODE_*` still read with a deprecation warning through v0.0.19; removed in v0.0.20).
+  - Home directory: `~/.t3` → `~/.bcode` (auto-migrated on first launch).
+  - Package scopes: `@t3tools/*` → `@bcode/*`.

+  - Linux desktop entry: `t3code.desktop` → `bcode.desktop`.
+  - localStorage keys: `t3code:*` → `bcode:*` (auto-migrated on first launch).
+  - Desktop internal protocol scheme: `t3://` → `bcode://`.
+- **Internal identifiers kept as-is** (upstream compatibility or legacy migration):
+  - `LEGACY_USER_DATA_DIR_NAME = "T3 Code (Alpha)"` / `"T3 Code (Dev)"` — pre-T3 electron userData path.
+  - `USER_DATA_DIR_NAME = "t3code"` / `"t3code-dev"` — electron's current userData subdir; a deliberate non-rename to preserve existing installs' window state, cookies, and renderer cache. May be renamed in a later cleanup.
+  - `LEGACY_T3_HOME_DIR_NAME = ".t3"` — read by the migration module only.
 - **Icons/logos**: Reuse existing assets for now.
 
 When writing new code, use "BCode" in anything a user would see and the existing internal identifiers for everything else.
