fix: Deno 2 compatibility and ignore patterns support

[nLight]

Fixes for running on Deno 2:

• Fix dependencies import in deno.jsonc
• Fix startup order: CouchDB peers init before storage peers
• Add ignore patterns support for PeerStorage (glob-based filtering)
• Add node-fetch-native dependency for fetch compatibility
• Make Hub.start() async to properly await peer initialization

Note: pouchdb-fetch requires manual patching after deno install to use native fetch instead of node-fetch for Deno compatibility.

Bug found: offline scan hangs when vault contains .git/ directory

When scanOfflineChanges: true and the vault contains a .git/ directory with thousands of objects, the offline scan hangs because isChanged() is called for every file before the ignore check. The shouldIgnore() in dispatch() is never reached.

Fix: Pass skip regexps to walk() so ignored directories are never traversed:

const ignorePatterns = this.config.ignore ?? [];
const skipRegexps = ignorePatterns.map(p => {
    const escaped = lP.replace(/[.*+?^${}()|[\]\\]/g, "\\$&");
    const pattern = p.replace(/\*\*/g, ".*").replace(/\*/g, "[^/]*");
    return new RegExp(`${escaped}/${pattern}`);
});
for await (const entry of walk(lP, { skip: skipRegexps })) {

Config example: "ignore": ["**/.git/**", "**/node_modules/**"]
