fix(content): retry bitswap peer discovery per CID

[replghost]

Fixes #219.

Fresh application loads can race Bulletin peer discovery. bitswap_v1_get may return -32810 No connected peers have the CID requested before a provider attaches, even when the CID is available.

This change:

• retries -32810 with bounded backoff for each requested CID;
• counts provider-discovery failures separately from other transient errors;
• caps retry sleeps at the total request deadline;
• reports the CID and exhausted failure/attempt counts;
• prevents slow preimage lookups from overlapping across polling ticks.

Coverage includes initial and child-CID recovery, concurrent requests, mixed transient errors, persistent discovery failure, total-budget enforcement, and non-overlapping preimage polls.

Verification:

• bun run test -- tests/bulletin-bitswap.test.ts tests/preimage.test.ts in packages/ui — 13 passed
• bun run typecheck in packages/ui
• bun run lint in packages/ui
• Prettier check for all four modified files
