fix(client): raise project-open & directory-suggestion timeouts for large repos (#1620)

openProject 10s->60s and getDirectorySuggestions 10s->30s + debounce the
project-picker query 250ms. On large local repos the daemon's path-resolve and
home-tree scan take several seconds; firing per-keystroke against a 10s timeout
raced the suggestion list to empty (e.g. ~/gi found a hit but ~/gith blanked)
and surfaced a spurious 'Timeout waiting for message (10000ms)' on add.
