- Rename Peertube module references to Peer_tube in client library
- Refactor bushel_peertube to use generated Peer_tube types
- Remove hand-coded JSON codecs in favor of generated ones
- Add helper functions to extract values from Jsont.json for untyped fields

- Add default value support: extract JSON defaults and generate OCaml literals
for bools, ints, floats, strings, enums, null, and empty arrays
- Generate constructors with optional params using ?(name=default) syntax
- Generate jsont codecs with ~dec_absent:default for absent field handling
- Add runtime validation for strings (minLength, maxLength, pattern),
numbers (minimum, maximum, exclusiveMinimum, exclusiveMaximum),
and lists (minItems, maxItems, uniqueItems)
- Add field-level union types for primitive oneOf/anyOf schemas
- Handle forward references in circular dependencies with Jsont.json fallback
- Improve topological sort to handle cycles gracefully
- Regenerate immich and peertube clients with new features

Major enhancements to the OpenAPI code generator:

1. allOf composition support:
- Added resolve_schema_ref to look up referenced schemas
- Added flatten_all_of to recursively merge properties from composed schemas
- Added expand_schema to resolve allOf before generating types
- VideoDetails now contains all 50+ fields from Video merged in

2. Property type reference resolution:
- Updated type_of_json_schema to handle allOf with $ref in properties
- Properties like "id: allOf: [$ref: '#/components/schemas/id']" now
resolve to the correct type

3. Nullable field handling:
- Added is_nullable tracking to field_info
- Added nullable combinators to runtime (nullable_any, nullable_string,
nullable_ptime, nullable_int, nullable_float, nullable_bool)
- Fields marked "nullable: true" use these combinators to handle both
absent and explicit JSON null values

4. public_name in generated dune files:
- Libraries are now public by default for proper dependency management

The peertube library now generates fully typed records with proper
accessors for all schemas, including composed types like VideoDetails.

The code generator was ignoring parameters that use $ref references
(e.g., $ref: '#/components/parameters/idOrUUID'). This caused path
template parameters like {id} to not be substituted in the generated
code.

Changes:
- Add param_name_from_ref to extract parameter name from $ref string
- Add resolve_parameter to look up referenced parameters in components
- Update analyze_operation to accept spec and path_item_params
- Merge path_item parameters with operation parameters
- Add explicit type annotation for path_item to fix type inference

The peertube library is regenerated with this fix, so get_video and
similar endpoints now correctly accept their path parameters.

- Fix topological sort to ignore self-dependencies
- Fix newline before @param in generated doc comments
- Generate PeerTube library from official OpenAPI spec (v8.0.0)

Git operations:
- Add retry logic with exponential backoff for HTTP 5xx errors
- Retry on RPC failures, curl errors, connection issues
- 3 retries with 2s/4s/8s delays before failing
- Apply to clone, fetch, pull, push, and subtree operations

Sources registry (sources.toml):
- New module for tracking package URL overrides
- default_url_base for deriving URLs from subtree names
- Per-package entries with url, upstream, branch, reason

Verse config:
- Add knot field for git push server (e.g., "git.recoil.org")
- Default to "git.recoil.org" if not present in config
- Auto-write knot to config file if missing

URL handling:
- Remove hardcoded anil.recoil.org references
- Derive git push server from handle or use configured knot
- Generic SSH URL normalization in forks.ml

Sync resilience:
- Skip failed clones in merge/subtree phases instead of crashing
- Track successfully fetched repos separately from failures
