* Bound public rate-limit buckets against attacker-keyed growth.
Keep the NIP-13 PoW sender bypass, skip content-bucket minting on
sender reject, and evict idle/oldest entries at a hard cap.

* Stop Cashu-looking text from skipping long-message guards.
Oversized public content always collapses and takes the plain
formatting path so remote tokens cannot force layout/regex DoS.

* Cap teleported geohash participant markers.
Bound the set with FIFO eviction, clear it on channel switch, and
prune markers that leave the visible participant list.

* Bound untrusted Nostr relay frames and event tags.
Reject oversized inbound messages before JSON parse, cap tag
arrays/values at decode, and stop logging raw tag contents.

* Fail soft when Noise handshake state is unexpectedly missing.
Replace the initiator startHandshake force unwrap with a guard
that throws invalidState instead of crashing.

* Cap geohash nickname cache from remote Nostr events.
FIFO-evict at capacity, clear on channel switch, and prune
nicknames that leave the visible participant list.

* Avoid overlapping exclusive access in the rate limiter.
Make bucket helpers static so inout dictionary updates do not
conflict with a mutating call on self.

* Fix rate-limiter tests for mutating allow under #expect.
Call allow outside the macro so Swift Testing does not capture an
immutable copy of the struct.

* Drop unused WebSocket data helper; reset rate limiter on panic wipe.
dataWithinInboundLimit replaced the unbounded path, and panic clear
should not leave public intake buckets behind.

Refactor message formatting logic into a dedicated, testable class:
- Create MessageFormattingEngine with Patterns enum (precompiled regexes)
- Create MessageFormattingContext protocol for dependency injection
- Extract extractMentions(), containsCashuToken(), and pattern matchers
- Add 28 comprehensive tests for formatting utilities
- Update ChatViewModel to conform to MessageFormattingContext
This prepares for further message formatting extraction and makes
regex patterns and utility functions testable in isolation.
