Completes the rebrand per direction: LANGFLOW_/LANGFLOW -> FLOW_/FLOW (env vars,
headers), langflow_ -> flow_ (settings fields, local vars), camelCase identifiers
(LangflowClient/Logo/HTTPError, builtWithLangflow, getLangflowDesktop) -> Flow*,
and all remaining bare tokens. Fixed the identifier-space hazard (Langflow ->
'Hanzo Flow' is prose-only; in code it collapses to Flow so no identifier gains a
space). compileall of flow + lfx is clean.
Repo-wide langflow now = 4, all the protected MIT attribution to langflow-ai/
langflow in README (legally required; deliberately preserved).
Breaking (per no-backwards-compat / forward-perfection): the LANGFLOW_* env-var
prefix is now FLOW_* — deployments must update their env. CI's uv + frontend
build is the runtime gate.
Docs corpus (Langflow->Hanzo Flow, upstream URLs langflow-ai/langflow->hanzoai/
flow, docs.langflow.org->docs.hanzo.ai), starter-project template help-URLs, CI
workflows, and test files. Remaining 'langflow' repo-wide is now dominated by
LANGFLOW_* env-var names + langflow_ settings fields — the config-boundary layer
deliberately preserved pending a coordinated FLOW_/HANZO_ alias-with-fallback
(renaming them blind breaks every deployment).
The concurrent rebrand left src/backend/base/langflow alive with 34 UNIQUE
unmigrated files (a flow_events service, the WatsonX-Orchestrate deployment
adapter, the flow_version_deployment_attachment DB model + tests) that flow/
never received, plus 152 files still importing `langflow` and 137 more with
`langflow.<mod>` string module paths (import_module/monkeypatch targets).
- Migrated all 34 unique files langflow/ -> flow/ at matching paths (dropped
langflow/api/v1/__init__.py, superseded by flow/'s).
- Deleted the emptied src/backend/base/langflow package.
- Repointed every `from langflow`/`import langflow` (152 files) and every
`langflow.<mod>` string path (137 files) to `flow`.
Verify: 0 `from/import langflow` and 0 `langflow.` module refs remain in *.py;
compileall of src/backend/base/flow + src/lfx/src parses clean. Runtime import
resolution + the uv test suite is the CI gate (the module tree is now internally
consistent: every moved model/service resolves under flow/).
Remaining (follow-on commits): runtime identifier strings (MCP server names),
the langflow-base/langflow-sdk distribution names, and the docs corpus.

* tag-hidden-endpoints
* update-scripts-and-specs
* fix: nightly now properly gets 1.9.0 branch (#12215)
before it was attempting to pull release-notes as letters are alphanumerically after numbers when we sort -V then grab tail
now we only look at branch names that follow the pattern '^release-[0-9]+\.[0-9]+\.[0-9]+$'
* docs: add search icon (#12216)
