Fix all lint/build issues on main branch (closes #13)

Browse Source 
- Resolve duplicate method declarations (CreateUser, GetUserByToken,
  GetUserByNick) between db.go and queries.go by renaming queries.go
  methods to CreateSimpleUser, LookupUserByToken, LookupUserByNick
- Fix 377 lint issues across all categories:
  - nlreturn (107): Add blank lines before returns
  - wsl_v5 (156): Add required whitespace
  - noinlineerr (25): Use plain assignments instead of inline error handling
  - errcheck (15): Check all error return values
  - mnd (10): Extract magic numbers to named constants
  - err113 (7): Use wrapped static errors instead of dynamic errors
  - gosec (7): Fix SSRF, SQL injection warnings; add nolint for false positives
  - modernize (7): Replace interface{} with any
  - cyclop (2): Reduce cyclomatic complexity via command map dispatch
  - gocognit (1): Break down complex handler into sub-handlers
  - funlen (3): Extract long functions into smaller helpers
  - funcorder (4): Reorder methods (exported before unexported)
  - forcetypeassert (2): Add safe type assertions with ok checks
  - ireturn (2): Replace interface-returning methods with concrete lookups
  - noctx (3): Use NewRequestWithContext and ExecContext
  - tagliatelle (5): Fix JSON tag casing to camelCase
  - revive (4): Rename package from 'api' to 'chatapi'
  - rowserrcheck (8): Add rows.Err() checks after iteration
  - lll (2): Shorten long lines
  - perfsprint (5): Use strconv and string concatenation
  - nestif (2): Extract nested conditionals into helper methods
  - wastedassign (1): Remove wasted assignments
  - gosmopolitan (1): Add nolint for intentional Local() time display
  - usestdlibvars (1): Use http.MethodGet
  - godoclint (2): Remove duplicate package comments
- Fix broken migration 003_users.sql that conflicted with 002_schema.sql
  (different column types causing test failures)
- All tests pass, make check reports 0 issues
