Adds IndexKey::MetricDeclaration handling: DeclareMetric/RemoveMetricDeclaration
engine messages and a MetricDeclarations query, mirroring the pattern from ticket
001's param declarations. Params are derived from inline named capture groups on
the metric's own regex for v1 (referencing existing ParamDeclarations is left for
a future ticket). Validates the regex and every RegexToMetricPrimitiveMatcher's
capture-group reference at declaration time, reporting all bad matchers at once.

Introduces a standalone src/filter_parser.rs module (no dependency on
engine/index types) that parses the FilterBar query language into a
FilterExpr AST using a pest grammar (src/filter_parser.pest). Supports
regex("...") searches, metric_name[param] <op> value comparisons,
reserved sequence/timestamp metrics, and and/or combinators with
correct precedence (and binds tighter than or) and parenthesized
sub-expressions. Evaluation against real log data is left to a later
integration ticket.

Introduces src/settings.rs with a single, process-wide Settings struct
(colour scheme, CSS entries shaped for imported-vs-linked, and a
profiles placeholder for ticket 009), JSON-serialized via serde_json to
keep deps minimal. Default settings path is computed with the
directories crate (ProjectDirs::from("", "", "ottyl")) and overridable
via a new --settings-path CLI arg. Settings::load creates and persists
a default file on first run; Settings::save persists changes.
Wires a single Arc<Mutex<Settings>> into main() and threads it through
api::router as an additive ApiState field for tickets 010/011 to build
on.

Standalone module (no engine/index/filter-grammar deps) that normalizes
relative humantime (5h, -3m), absolute time-of-day (12:00, resolved to
today in UTC), and full date/RFC3339 literals (2024-01-15,
2024-01-15T12:00:00Z) into a single Timestamp, given a passed-in `now`
for testability. Adds humantime and chrono dependencies.

Implements the ParamDeclaration slice of the primary index: DataValue::ParamDeclaration
holds a regex + named capture group + MetricPrimitiveKind, stored under
IndexKey::ParamDeclaration{name} between LogParamSplit and ParamMetricSplit.
EngineMessage gains DeclareParam (validates the regex compiles and the capture
group exists before storing, returning a clear error otherwise) and
RemoveParamDeclaration; EngineQuery gains ParamDeclarations to list them back out
as ParamDeclarationDto. No API wiring yet (separate ticket).
