v1.11.0 --- Parsing shortcuts, deterministic date cleaning, and SQL token upgrades¶

Highlights¶

New parsing façade: one-line helpers for Boolean, Float, Decimal, and Date.
Deterministic date cleaning: CleanAndParse, CleanAndParseAsString, strict YYYYMMDD prefix path, and 100% tests.
Boolean parser++: extended tokens (on/off, y/n, t/f) and explicit nil rejection.
SQL Builder/Token overhaul: Column → Field, FieldCollection, deterministic NewField inputs, and Postgres/Base dialects with tests.

f45ff2a refactor(common): rename math package → extension
c8ca52f refactor(token): make Field constructor inputs deterministic; improved raw-alias handling
45da5dc refactor(token): rename Column → Field and add tests
9fc782f refactor(builder): improve builder.Select, delegate field resolution to token.Field, add select.GetFields()
e722fdc refactor(builder): move builder to internal/builder

math → extension package rename
token.Column → token.Field
builder.Select changes: use select.Fields(...) and select.GetFields()
Date parsing: use CleanAndParse with options, or StrictYYYYMMDDOptions() for strict feeds
