chore(deps): bump LXMF-swift to 0.4.0 + reticulum-swift to 0.3.0 (#73)

LXMF-swift 0.4.0 (PR #7 — perf/stamper-parallel-primed-digest, merged):
  - Parallel stamp generation (LXStamper TaskGroup, 8 workers, primed
    SHA256 digest) — cost=16 from multi-minute to ~1-2s on iPhone.
  - PROPAGATED state machine fixes: drops wrong link.identify(); wires
    RESOURCE_PRF to .sent (not .delivered); ERROR_INVALID_STAMP handler
    via pendingPropagationSends FIFO + pendingPropagationRejections
    set; handlePropagationAccepted + handleOutboundResourceFailed with
    awaited DB writes that preserve deliveryAttempts budget.
  - DIRECT path: self-send identity resolution before path table;
    drops premature link.identify(); broadcast-relay-only self-echo
    gate; DIRECT resource crash-recovery parity with PROPAGATED.
  - Stamp-rejected resource short-circuit prevents retry-loop spam.

reticulum-swift 0.3.0 (PR #16):
  - HEADER_2 link DATA conversion fix.
  - sendLinkData signature: destinationHash param removed (breaking).

Package.swift, pbxproj, and Xcode-shared Package.resolved all updated.
Build verified: xcodebuild for iOS Simulator, CODE_SIGNING_ALLOWED=NO,
BUILD SUCCEEDED. Smoke pipeline (PROPAGATED/DIRECT/OPP bidirectional
with Mac echo bot) to follow on PR ready→draft transition.
