fix(config+vault): per-device Obsidian config (kills the perpetual write-conflict) + hide dotfiles

Dogfooding follow-up to the lazy loading in this PR. Two real-machine problems:

1. `.obsidian` config kept raising write-conflicts, blocking work. Root cause
   (read from the code, not guessed): a conflict fires when the read cache's
   mtime ≠ the remote file's mtime (SftpDataAdapter.writeBuffer). The daemon
   compares mtime as UnixMilli on both sides, so a single device's sequential
   note edits can't perpetually conflict. What CAN: app.json / appearance.json /
   core-plugins.json / hotkeys.json were the only config files NOT redirected
   per-client — they sat at the shared identity path, so two sessions (or one
   device across reconnects) both wrote the SAME remote file and every settings
   save tripped PreconditionFailed on the other's mtime.

   Fix = make them per-device: add the four to DEFAULT_PRIVATE_PATTERN_BASENAMES
   so PathMapper redirects each into this client's `<configDir>/user/<id>/`
   subtree (exactly what workspace.json/graph/cache already do). No shared path
   → the conflict is impossible by construction. The existing shared-config
   round-trip keeps working — now on the per-client path, so each machine gets
   its own remote backup + cross-session persistence. This is the user's own
   ask: "config should be settable per accessing device".

2. `.julia` (and other dot-dirs) cluttered + slowed the tree. Now:
   - BulkWalker drops dot-prefixed entries from every walk result (full walk AND
     each lazy per-folder deepen), keeping only the vault config dir — matching
     Obsidian's own default of hiding dot-names. A dot-DIR hides its whole
     subtree, not just its row.
   - DEFAULT_WALK_IGNORE_DIRS gains `.julia .cargo .rustup .npm .conda .gem` so
     the daemon prunes these huge caches server-side (never walked/transferred),
     the perf half of "hide `.julia` by default".

tsc / lint clean; vitest 1204 passed (+ per-device PathMapper assertions and a
BulkWalker dotfile-filter test; config round-trip integration tests still green
because seed-write and pull-read go through the same PathMapper). Ships beta.17.
