fix(organization): pass endpoint context to organization delete hooks

Vercel just adopted Better Auth — the auth stack now behind a massive chunk of the web. In the organization plugin, the beforeDeleteOrganization and afterDeleteOrganization hooks silently dropped their ctx argument. Every user reading ctx got undefined. No error. No warning. Just a broken pattern the docs told you to write.

Fixed the type signatures, patched the two call sites in routes/crud-org.ts, forwarded ctx through the @better-auth/stripe wrapper so orgs + stripe users would get the fix too, corrected the docs example, and added a regression test.

Result: 102 organization tests pass. 173 stripe tests pass. Types clean. Ships to every Vercel app using Better Auth's organization delete hooks.

Design-pattern fixes in an LLM insurance proxy

Brolly routes LLM calls through Mesh API with cost-cascade routing and mid-session failover.

• #30 — Shared-mutable-state bug: DEFAULT_PRICE returned by reference, so any caller mutating it poisoned every subsequent request. Fixed with defensive copy per call.
• #31 — Hardened the usage summarizer against events with invalid timestamps. Skip instead of crash. Defensive-filter at the boundary.

[DOC] Fix pad_length / truncated_length naming and test docstring in unequal_length

Naming + docstring fix in the unequal_length utility of a widely-used time-series ML library. Small touch, but the kind of thing that unblocks the next dev reading the source.
