zeekay 0144f80def consensus: collapse profile registry to strict / permissive / fips 
PQ mode is binary. The profile registry is collapsed to three
canonical bundles:

  0x01 ProfileStrictPQ   ("STRICT")     — production PQ chains
  0x02 ProfilePermissive ("PERMISSIVE") — testnet / devnet
  0x03 ProfileFIPS       ("FIPS")       — FIPS-aligned superset

Removed pseudo-profiles: HybridProfile, ClassicalProfile, BLSProfile,
ZooStrictPQProfile, HanzoStrictPQProfile, QuasarStrictPQProfile,
AnnulusStrictPQProfile. Chains that need classical primitives pin
ForkClassicalCompatUnsafeProfile (0x80) at the byte layer and own
the audit consequence.

(*ChainSecurityProfile).IsPQ() is the single canonical predicate.
Profile string surface tracks the byte registry exactly: "strict",
"permissive", "fips".

Cross-brand scrub: dropped "Hanzo mesh" doc-comments in pq_mode.go
+ pq_mode_test.go + witness_floor_test.go in favor of "Lux mesh".
Dropped Lux/Zoo/Hanzo enumeration in account_id.go. account_id_test.go
uses fork byte (0x80) instead of zoo/hanzo profile IDs. qblock.go
references LP-0079 instead of cross-org HIP path.

zeekay 04ce8745ee consensus: Quasar cutover to LSS-Pulsar + post-Feb-28 batch 
Squashed batch covering all post-Feb-28 consensus work, capped by the
LSS-Pulsar cutover (task #53):

- Quasar cutover from upstream Corona to LSS-Pulsar adapter:
    go.mod: drop direct require github.com/luxfi/corona; add
            github.com/luxfi/pulsar + github.com/luxfi/threshold;
            local replaces => ../pulsar, ../threshold
    epoch.go: InitializeEpoch → keyera.Bootstrap; RotateEpoch →
              lss.DynamicResharePulsar gated by activation cert
              verification under unchanged GroupKey
    quasar.go, grouped_threshold.go: import swap corona → pulsar
    reshare_epoch.go: production wiring; QUASAR-PULSAR-ACTIVATE-v1
                      domain prefix; ReshareEpoch + RefreshEpoch
    EpochKeys: gains KeyEraID, Generation, RollbackFrom (LP-105)
    BundleSigner: re-derives Lambda for participating subset
    258 quasar tests pass.

- Earlier post-Feb-28 work (gofmt linter fixes across protocol files,
  METASTABLE_SIGNED_QUERIES.md doc, MLDSAProof rename across 7 test
  files) included in the squash.

Hash profile: consensus passes nil to resolve to Pulsar-SHA3 default
(LP-105 / pulsar/hash). Activation message canonical bytes bind
chain_id, network_id, key_era_id, generation, group_id, epoch, set
hashes, thresholds, group_pk_hash, nebula_root, hash_suite_id,
implementation_version, variant, reshare_transcript_hash —
all under TupleHash256("PULSAR-TRANSCRIPT-v1", ...).

Vocabulary alignment with LP-105 (Lux Finality Stack lexicon):
  Photon (vote) → Beam (BLS) → ML-DSA (PQ identity) →
  Pulsar (PQ threshold kernel) → Pulse (cert over Nebula root) →
  Prism (composition verifier) → Horizon (finality boundary) →
  Quasar (full consensus).
