* test: reproduce Cmd+N snapshot workspace lifetime race
* fix: retain snapshot workspaces through Cmd+N creation
* fix: repair workspace lifetime regression test
* fix: extract workspace config through self to avoid Xcode 16.x ARC crash
The snapshot approach (c1998e34) navigated workspace → panel → surface
through local variables. Xcode 16.4's -O ARC optimizer aggressively
elides retains on these locals through inlined call chains, causing
use-after-free on every Cmd+N in CI-built nightlies.
Fix: extract preferredWorkingDirectory and inheritedTerminalFontPoints
through self (always retained) BEFORE capturing locals. The snapshot
is now purely value-typed with no Workspace references held in locals.

CmuxWebViewKeyEquivalentTests.swift grew to 15,907 lines with 100+ test classes.
Swift compiles per-file, so this single file serialized all type-checking onto one
compiler process, pushing CI past the 20-minute timeout after core-file changes.
Split into 10 domain-based files (1k-3k lines each) so Xcode can compile them in
parallel. Also bump timeout-minutes from 20 to 30 for headroom, stream xcodebuild
output via tee instead of capturing to a variable (makes CI logs debuggable), and
add 5 test files that were missing from the pbxproj Sources build phase.
