Bump version to 0.11.0

[jeremy]

Release prep for v0.11.0 — make bump VERSION=0.11.0 (10 version files + lockfiles).

v0.11.0 ships two breaking changes plus the OAuth/transport work since v0.10.0:

• Breaking: GetEverythingBoosts removed — BC5 withdrew the account-wide boosts feed (Remove GetEverythingBoosts: BC5 withdraws the account-wide boosts feed #504; 226→225 operations).
• Breaking: retry-attempt reductions from Kotlin applies per-operation maxAttempts as a floor; Ruby ignores it entirely #485 — Kotlin callers' caps now clamp to per-op ceilings (and lowered caps are honored); Ruby governed GETs stop retrying 500 and honor per-op ceilings (Retry ceilings everywhere: Kotlin honors the caller cap, Ruby enforces the per-op block #515).
• Subscribe + EnableCardColumnOnHold flagged naturally idempotent — they now retry on 429/503 (Flag Subscribe and EnableCardColumnOnHold as naturally idempotent #514).
• OAuth device flow + RFC 8707 + transport hardening, retry hardening (Retry: hand out a copy of the declared status set, and run the parity guard in CI #500/TypeScript: one request lifecycle, so every attempt is observed exactly once #503/fromCache means served from the ETag cache, so require the header that proves it #505/Run the wrapper field-level drift gate in CI #506).

Release proceeds per RELEASING: merge this, then make release VERSION=0.11.0 from main.

Holding this open — more fixes are landing ahead of 0.11.0. Will refresh against main once they're in, then release.
