chore(release): v0.2.0 — colour/climate assembly + GA-intent noise reduction

Bump version 0.1.2 -> 0.2.0 (pyproject + __init__). Promote the
Unreleased changelog section to [0.2.0] — 2026-06-30. Scrub a client
city label from two test comments (provenance note only, no PII/topology).

+**Colour/climate entity assembly and GA-intent noise reduction.** Two feature tracks
+shipped together, both driven by real ETS projects: full colour-light (RGBW/RGB/CCT) and
+KNX `climate` entity generation with a status-pairing (B1) correctness fix, and a GA-intent
+classifier that stops intentional non-functional addresses from raising false errors. On a
+real 685-GA Zennio project the intent work cut false errors **29 → 6** and missing-status
+noise **79 → 45** while preserving all 12 genuine `dpt_mismatch_co` catches.

 ### Added
 - **Colour lights, climate entities and a status-pairing fix** (Track A), driven by the real
   signed demo and a 685-GA Zennio project.
