Add the new x/cover module (Cover Pool runtime) implementing P1 of the
v0.7 milestone: CoverPool/CoverFeeTag/CoverCall types with the 4 GRILL-
ratified locked consts (CoverReserveFloorAnnualContribX=1.5,
CoverReserveCeilingAnnualContribX=2.5, CoverStandingGateTrusted=4.0,
CoverStandingGatePreferred=4.5), the 8-category/3-phase CoverCategory
enum with D-086 FactoryAllowedPhases=[Phase2]-only default, three Msg*
types (LaunchCoverPool/RouteCoverFee/FileCoverCall) with full sdk.Msg
impls, store-backed Keeper with 4 G-003 expected-keeper shims
(StandingKeeper/WatcherKeeper/BondKeeper/StillKeeper), and three
handlers enforcing the D-077 Standing gate, D-086 category phase check,
REQ-047 reserve floor + below-floor auto-pause (D-089(1) Still
invocation), and REQ-050 category-tag match.
Add the x/cover/firewall subpackage (Anti-Crowding-Out firewall, D-079/
D-088): a stdlib-only leaf checker enforcing RightNoTaxOnPersonalStash
by rejecting Cover-Fee routing to the Root-Pool operating-expenses
destination (defense in depth with the lexicon meta-test).
Add the lexicon_meta_cover meta-test (4th lexicon firewall, D-088):
scans x/cover/**/*.go for both lexicon.FindBannedTerm (10 project-wide
terms) AND lexicon.FindCoverBannedTerm (4 Cover-specific terms), with
G-013 walk-coverage + G-009 self-test tables.
Add lexicon.CoverBannedTerms()/FindCoverBannedTerm()/
SyntheticCoverBannedStrings() helpers (additive to the existing
project-wide BannedTerms — no changes to existing helpers).
Apply D-088(3) optional doc-fix: replace 'insurance-like' with
'Cover-like' in x/pact/types docstrings.
Coverage: x/cover/types 97.8%, x/cover/keeper 94.1%, x/cover/firewall
100.0%. go.mod/go.sum unchanged (G-006/G-028). All existing tests pass.
REQs: REQ-046, REQ-047, REQ-049, REQ-050
