The Studio design system, widgets and helpers carried a Fai* / fai_
prefix (FaiSpace, FaiColors, FaiTheme, FaiLog, 17 fai_*.dart files, the
faiBinary* l10n keys). Studio is the Ch∆In product, so rename them to
Chain* / chain_ — carefully preserving English fail/failure/failed.
Also fix stale references: the 'fai' binary in l10n strings -> 'chain',
FAI_* env vars (FAI_BIN/DATA_DIR/MODULES_DIR/TODAY/BOOTSTRAP_TOKEN) ->
CHAIN_*, fai_platform -> fai_chain, fai_hub -> chain_hub. Vendor
security-hook tooling (FAI_BANNED_TERMS_FILE) + the .fai bundle ext left.
flutter analyze + test: clean (20 passed).

Studio is the Ch∆In product's GUI, not a F∆I-vendor app. Rename the
Flutter package, all package: imports, and the build identity across
platforms: linux/windows CMake BINARY_NAME + project, Windows Runner.rc
fields, macOS PRODUCT_NAME / bundle id (ai.flemming.chain.chainStudio) /
.app + scheme BuildableName. Update the client-SDK + flow-editor deps to
their renamed chain_* packages (path + git URL). Company/copyright fields
now read Flemming.AI. flutter analyze: clean.

FaiLog used to compute its destination directly from HOME, which
made it impossible to test without scribbling on the operator's
real ~/.fai/logs/. Adds a static testPathOverride seam tagged
@visibleForTesting so the singleton can be redirected at a per-
test temp file.
The new test/fai_log_test.dart covers:
- append() writes one JSON-shaped line per event
- context field round-trips when supplied
- tail() returns oldest-first
- tail(maxLines:) caps and keeps the newest entries
- rotation moves the previous log to .log.1 past 256 KiB
- path getter honours the override
- writes to an impossible path do not throw — best-effort
contract that protects the UI from log-write failures
Production behaviour is unchanged: when the override is null
the path getter still computes from HOME/USERPROFILE.
