C1+C7: Cache purge now passes user_id and works for view-path
mutations. Extracted _purge_cache_for_invalidation() shared helper
used by both RPC and view-path branches.
C2: initSession retries 3x with backoff. Resets on total failure
so next call tries again instead of permanently broken CSRF.
C3: SSR template backend injects __MIZAN_SSR_DATA__ script tag
with serialized props for client-side hydration.
C4: SSR bridge uses _write_lock to serialize stdin writes from
concurrent Django threads. Prevents JSON interleaving.
C5: SSR bridge registers atexit handler for process cleanup.
No more orphaned Bun processes on Django reload/shutdown.
H1: pendingScoped changed from Map to Array — multiple scoped
invalidations for the same context no longer overwrite.
H2: registerContext uses stableKey() (sorted JSON) instead of
bare JSON.stringify. Property order no longer matters.
H4: Named context providers skip refetch if SSR data exists
(matches global context behavior).
H10: _meta always assigned as fresh dict, preventing shared-dict
mutation across ServerFunction subclasses.
373 Django + 33 React tests pass.
