When bd cook encounters a circular extends chain (A extends B extends A),
the error message now shows the full chain: "cycle-a -> cycle-b -> cycle-a"
instead of just "circular extends detected: cycle-a".
This makes debugging circular dependencies much easier by showing exactly
which formulas are involved in the cycle.

Add DefaultMaxExpansionDepth constant and depth tracking in expandStep
to prevent runaway nested expansions. The limit applies to template
children during expansion.
Changes:
- Add DefaultMaxExpansionDepth = 5 constant
- Update expandStep to track depth and return error when exceeded
- Update ApplyExpansions callers to handle errors
- Add TestExpandStepDepthLimit test for depth limiting

Add expand and map operators that apply macro-style template expansion:
- expand(target, template) - replace a single step with expanded template
- map(select, template) - replace all matching steps with expanded template
The expansion formula type (e.g., rule-of-five) uses a template field with
{target} and {target.description} placeholders that are substituted when
applied to target steps.
Changes:
- Add Template field to Formula struct for expansion formulas
- Add ExpandRule and MapRule types to ComposeRules
- Implement ApplyExpansions in new expand.go
- Add LoadByName method to Parser for loading expansion formulas
- Integrate expansion into bd cook command
- Add comprehensive tests

- Change file extension from .formula.yaml to .formula.json
- Replace gopkg.in/yaml.v3 with encoding/json in parser
- Remove yaml struct tags, keep json tags only
- Update all test cases to use JSON format
- Update documentation references

- bd-hr39: Add `needs` field to Step as alias for depends_on. Converts
to blocking dependencies between sibling steps during cooking.
- bd-j4cr: Add `waits_for` field to Step. Values: all-children or
any-children. Preserved as gate:<value> label during cooking.
- bd-47qx: Add --prefix flag to bd cook command to prepend a prefix
to proto IDs, enabling use of project prefixes like gt-.
Includes validation, dry-run output, and comprehensive tests.

Fixes from self-review of formula parser and bd cook:
1. Atomicity: Add cleanup on failure in cookFormula - if labels/deps
transaction fails, delete the already-created issues
2. Validation: Add recursive depends_on validation for child steps
and validate priority ranges for children
3. Documentation: Mark unimplemented fields (Expand, ExpandVars,
Condition, Gate) with TODO(future) comments
4. Thread safety: Add note that Parser is NOT thread-safe
5. Error messages: Track first definition location for duplicate ID
errors (e.g., "duplicate id at steps[1], first defined at steps[0]")

Implements a new formula system for defining workflow templates in YAML:
- internal/formula/types.go: YAML schema types for .formula.yaml files
- Formula, Step, VarDef, ComposeRules, BondPoint, Gate types
- Support for workflow, expansion, and aspect formula types
- Variable definitions with required, default, enum, and pattern
- internal/formula/parser.go: Parser with extends/inheritance support
- Parse formula files from multiple search paths
- Resolve extends references for formula inheritance
- Variable extraction and substitution
- Variable validation (required, enum, pattern)
- cmd/bd/cook.go: bd cook command to compile formulas into protos
- Parse and resolve formula YAML
- Create proto bead with template label
- Create child issues for each step
- Set up parent-child and blocking dependencies
- Support --dry-run, --force, --search-path flags
Example workflow:
bd cook mol-feature.formula.yaml
bd pour mol-feature --var component=Auth --var framework=react
