refactor(test): optimize VSCode test suite

Extract invokeCommand helper in commands.test.ts (-157 lines), add
COMMAND constant to types.ts to eliminate repeated string literals,
remove 3 low-value status-bar tests, add git detection unit tests (9),
FSP dispose test, and copyPath scheme guard test. Group syncFilesExclude
18 tests into 7 sub-describes for navigability. Rename mockTracker to
mockLocalIndexTracker for clarity.
