feat(db): architecture zone-bias + color-register-band tables + V-TT-06/07 (T-988)

Ratified content baked into systems.db as two new tables:
- architecture_zone_bias (57 rows): sparse per-template, per-zone_type
  token-weight overrides (integer bps), Miri-authored — the D-235 step-2
  zone bias. V-TT-06: every token must exist in that template's own
  visual_bundle axis.
- color_register_bands (28 rows): per color_register integer HSV bands
  (hue centidegrees, sat/val bps), Araminta-authored. V-TT-07: full
  catalog coverage + valid integer bounds (min<max, in range).

Both TOMLs registered in generator_sources (stamp coverage); DDL in
systems-schema.sql + migration.py; validation wired into import_economics
steps 18/19 and test_traits.py failure-branch units (make test-tooling).
systems.db regenerated + re-stamped.

+# ==========================================================================
+# Architecture zone-type bias table (T-988, D-235 step 2)
+#
+# D-235's BuildingExteriorTag derivation is 3 steps: (1) the district's
+# dominant trait template (D-232) filters the available token set per axis
+# via its own `visual_bundle`; (2) THIS FILE biases which of those
+# already-filtered tokens a building is likely to draw, keyed on the
+# building's FUNCTION (D-142 zone_type) — "an industrial block stays stone,
+# not corrugated metal, if the template's allow-list says so"; (3) density
+# sets setback_tier. This table is step 2 only.
+#
+# SPARSE / FALLBACK MODEL. This is deliberately NOT a full 28-template x
+# 31-zone_type x 4-axis matrix (3,472 cells). It authors only the cases
+# where cultural or functional logic genuinely demands a lean — a civic
+# building reaching for stone and colonnade, a market stall staying in the
+# lighter/cheaper register, a fishing quay pulling boardwalk over cobble.
+# Every (template, zone_type) pair NOT listed here — and every token within
+# a listed entry not given a weight — falls back to a UNIFORM draw across
+# the template's visual_bundle for that axis. Absence of an entry is not an
+# oversight; it means the template's own visual_bundle already tells the
+# whole story for that function, or (rarely, see note at end) the template
+# has no per-axis choice left to bias.
+#
+# OWNERSHIP. Same co-maintenance split as object_tag_vocabulary.toml
+# (Q-049's resolution: split by concern, not by file) —
+#   - Miri owns the CULTURAL/FUNCTIONAL rationale: which zone_type leans
+#     toward which already-allowed token, and why (the inline comment above
+#     each entry below).
+#   - Araminta owns VISUAL-COHERENCE tuning of the bps weights themselves
+#     (does the resulting draw distribution actually read well against the
+#     shipped art, does a "boost" ever starve a token to invisibility).
+#   This pass (T-988 content deliverable) is Miri's cultural-logic
+#   authoring pass with initial weights; Araminta's visual-coherence review
+#   of the weights is a expected follow-up, same pattern as her parallel
+#   `color_register_bands.toml` pass in this same ticket.
+#
+# SCHEMA. Integer basis points (D-010): 10000 = 1.0x the uniform baseline.
+# A weight above 10000 boosts a token above uniform likelihood; a weight
+# below 10000 (never authored as 0 — no hard excludes here, that's what
+# the template's own allow/block already did) suppresses it toward rare.
+# Only tokens already present in the template's own visual_bundle.<axis>
+# may appear (importer-validated, V-TT check) — this file never expands a
+# template's palette, only re-weights within it. Unlisted tokens/axes/zones
+# keep the uniform baseline.

+# Color register bands (T-988, D-235) — numeric HSV bands per D-232
+# trait-template `color_register` label. Turns the free-form palette-cue
+# string documented in object_tag_vocabulary.toml ("a palette cue, NOT an
+# ObjectTag") into an authored, sampleable numeric range.
+#
+# THE MODEL: each color_register gets ONE integer HSV band. The fill seed
+# picks a single (hue, sat, val) point uniformly within the band per
+# building — same register, same family feel, different building each time.
+# This is the register acting as intended (D-235): "always within the
+# template's register," never a fixed single color, never unbounded.
+#
+# INTEGER UNITS (D-010 — no floats, ever; determinism is save-critical
+# under D-227):
+#   hue  0..36000   centidegrees  (degrees x 100; standard 0-360 deg wheel)
+#   sat  0..10000   basis points  (0-100.00%)
+#   val  0..10000   basis points  (0-100.00%)
+# All three axes are closed [min, max] integer ranges, min < max, sampled
+# uniformly (no wraparound support — no band crosses the hue 0/36000 seam).
+#
+# SATURATION CEILING (visual-hierarchy discipline, not a hard schema rule):
+# every band in this file stays at or below sat = 3600 (36%). This keeps
+# building material color — structure, the least important read — clearly
+# under the saturation the project reserves for foreground signal (entity /
+# relationship color has historically run 40-60% in this project's palette
+# work). Buildings should never visually compete with the things standing
+# in front of them. Even the two "brightest allowed" cultural-accent
+# registers (bright_painted, falu_red_and_pine) stay under this ceiling.
+#
+# OWNERSHIP (Q-049 split, same as object_tag_vocabulary.toml): Miri owns
+# whether a register's cultural placement is right for its template/corridor
+# (the WHY); Araminta owns the numeric HSV authoring (the WHAT it looks
+# like) and the cross-register visual discipline (distinctness, saturation
+# hierarchy, mood). Changes to a band's numbers are Araminta's call; changes
+# to which register a template carries are Miri's. Add both together when a
+# new template ships a new color_register value.
+#
+# COVERAGE: every color_register value referenced by

+# clearly distinct from the file's several warm-whitewash bands above.
+# FLAGGED FOR MIRI: real-world Vietnamese heritage townscapes (Hoi An) skew
