Phase B2 follow-up: first-person voice across all TwinBee flavor files

Sweep of the remaining four twinbee_*.go flavor files (gm, resource,
ambient, housing). Every 'TwinBee [verb]' / 'TwinBee says' / 'TwinBee
notes' rewritten into first-person or implicit-subject voice. Jokes,
references, and pacing preserved; a few lines got slightly sharper
punchlines on the way through.

Files touched:
  - twinbee_gm_flavor.go        (~270 lines, all narration pools)
  - twinbee_resource_flavor.go  (~100 lines, harvest/fish/loot pools)
  - twinbee_ambient_flavor.go   (~40 lines, between-day ticker)
  - twinbee_housing_flavor.go   (7 lines; Thom Krooke 3rd-person and
                                 Pastel 1st-person voices preserved)

twinbee_npc_flavor.go intentionally untouched: those are Pete
announcements referring to TwinBee, which is correctly third-person
(different speaker).

DO-NOT-REWRITE headers replaced with voice-convention notes covering
future additions.
