feat(cover): P2 Cover-Charter + Pool Council + staging + Bill of Rights (D-090(1))

P2 of v0.7 extends x/cover with Cover-Charter + Pool governance hybrid +
category staging + the Anti-Capture Bill of Rights types (D-090(1)
temporal-gap fix — Bill of Rights types land HERE, not P5, so the dual
firewall is in place before any Charter can be signed).

New (x/cover/types/rights.go): RightID type + 13 Right* consts +
AntiCaptureBillOfRightsCount=13 locked const + 13 Waivable* bool consts
(all false) + RightIsWaivable() always false + AllRights()/AllWaivableFlags().

New structs: CoverCharter (REQ-052) + CharterAmendment (7-day cooling) +
PoolCouncil (REQ-062 — 3 Masons + Watcher observer; NO Anchor/MAB seat) +
CoverCallVote (majority requires Watcher observer present). CoverPool
extended with CharterRef + CouncilRef. D-086 DefaultParams [Phase2] ->
[Phase2, Phase3, Phase4].

New Msg*: MsgSignCoverCharter (D-090(1) WaivedRights gate at
ValidateBasic — mirrors MissionLockAmendmentRejected D-064),
MsgAmendCoverCharter, MsgElectPoolMason, MsgVoteCoverCall,
MsgAmendPoolStandingGate (D-090(3) dual check: floor at ValidateBasic +
handler), MsgEscalateReserveCeiling (12-month age check).

New handlers: SignCoverCharter, AmendCoverCharter (Proposed + ProposedAt),
ElectPoolMason (max 3), VoteCoverCall (Yes requires observer),
AmendPoolStandingGate (D-090(3) re-check), EscalateReserveCeiling,
CoolCharterAmendment + RatifyCharterAmendment lifecycle helpers.

New stores: charter/ council/ vote/ amendment/ + SetParamsOverride/Params().

Simtest cases (a)-(h): Charter signing + D-090(1) WaivedRights reject +
7-day cooling + election + vote observer + D-086 out-of-phase + ceiling
escalation + D-090(3) below-floor reject.

Lexicon: rights.go + msg_charter.go lexicon-clean (initial 'policy' hit
fixed -> 'invariant'). .lexicon_fixture SkipDir guard added to 3 lexicon
walks (fixes pre-existing cross-package test-isolation race).

G-003/G-006/G-028/G-024 intact. go.mod/go.sum diff EMPTY.
Coverage: types 98.9%, keeper 95.1%, firewall 100.0%.

REQs: REQ-048, REQ-052, REQ-062, REQ-065 (D-090(1) Bill of Rights types
for REQ-056 land here; P5 adds the ceremony)

+// Msg* types (REQ-052, REQ-062, REQ-056, REQ-048, D-090(1), D-090(3)). The
+// P1 Msg* types live in msg_cover.go; this file is the P2 extension
+// (separated for file-hygiene — the P1 file is already at ~280 lines).
+//
+// G-006 controlled exception: this file gains the cosmos-sdk import for
+// sdk.Msg (mirrors msg_cover.go — D-055; the invariant/lexicon tests in
+// *_test.go stay stdlib-only per G-024, isolated from this msg_*.go file).
+//
+// The six P2 Msg types drive the Cover-Charter + Pool Council + Cover Call
+// Vote runtime:
+//   - MsgSignCoverCharter: sign a Cover-Charter (the handler enforces the
+//     D-090(1) Bill of Rights gate at ValidateBasic: any WaivedRights
+//     element REJECTS the signing; persists the CoverCharter + Watcher
+//     attests the witness hash).
+//   - MsgAmendCoverCharter: file a Charter amendment (the handler creates a
+//     CharterAmendment with Status=AmendmentProposed; a separate ratify
+//     handler / simtest time-advance transitions it to Cooled then
+//     Ratified after the 7-day cooling).
+//   - MsgElectPoolMason: elect a Mason to the Pool Council (the handler
+//     adds the MasonReachID to ElectedMasonReachIDs, max 3 — a 4th is
+//     REJECTED).
+//   - MsgVoteCoverCall: vote on a Cover Call (the handler enforces the
+//     Watcher-observer-present check for a CallVoteYes — REQ-062).
+//   - MsgAmendPoolStandingGate: amend a Pool's Standing gate (D-090(3) dual
+//     check: ValidateBasic rejects NewGate < CoverStandingGateTrusted; the
+//     handler re-checks in defense in depth).
+//   - MsgEscalateReserveCeiling: escalate a Pool's reserve target to the
+//     CoverReserveCeilingAnnualContribX (REQ-048 — the handler enforces
+//     the 12-month age check: now - pool.CreatedAt >= 365 days).
+//
+// All cross-module refs are by-ID-string (G-003). The WaivedRights field
+// on MsgSignCoverCharter is []RightID (the RightID type from rights.go) so
+// the D-090(1) gate can type-check it.
+//
