feat!: lifecycle commands; remove deprecated surface

[designcode]

Summary

• Add tigris buckets lifecycle (alias lc) with list, create, edit for multi-rule lifecycle management (transitions and TTL/expiration with optional prefix filter), backed by the updated @tigrisdata/storage SDK.
• Introduce a generic removed / replaced_by mechanism on CommandSpec and Argument so the cli-core can intercept removed entries with a clean redirect message instead of "unknown command/option". Removed entries are hidden from --help and have no implementation file.
• Cut deprecated commands and flags from the surface; future major-version deletions are just spec edits.

Breaking changes

• tigris buckets set-ttl and tigris buckets set-transition are removed. Use tigris buckets lifecycle create / edit instead.
• tigris forks list and tigris forks create are removed. Use tigris buckets create --fork-of and tigris buckets list --forks-of.
• --region and --consistency flags on tigris mk, tigris buckets create, and tigris buckets set are removed. Use --locations.

Each removed entry exits with a redirect message pointing at the replacement; nothing fails silently.

Other cleanup

• Drop OperationSpec alias, ParsedPaths type, unused YAML anchors (consistency_options, region_options).
• update-docs and generate-registry skip removed entries automatically.
• bucket-info no longer renders the deprecated ttlConfig row; the TTL rule appears under Lifecycle Rules like any other rule.
• Unexport internal-only helpers from lib/buckets/lifecycle/shared.ts.

Test plan

• npm run lint and npm run format:check pass
• npm test passes (636 unit tests)
• npm run build succeeds
• Smoke check redirect messages: tigris forks, tigris buckets set-ttl, tigris buckets set-transition, tigris mk … --region, tigris buckets create … --region, tigris buckets set … --region, tigris mk … --consistency
• tigris buckets lifecycle --help lists only list, create, edit
• Manually exercise tigris buckets lifecycle create / list / edit end-to-end against a bucket
• tigris buckets get <bucket> shows TTL-shaped rules under Lifecycle Rules (no separate TTL row)

Note

Medium Risk
Medium risk because this introduces new lifecycle rule flows and changes CLI dispatch/help behavior (including hidden/removed commands and flags), which can break existing scripts if redirects or parsing differ from expectations.

Overview
Adds a new tigris buckets lifecycle command group (list, create, edit) to manage multi-rule bucket lifecycle configuration (transitions and TTL/expiration, optionally scoped by prefix), including shared validation/formatting helpers and updated bucket info rendering for lifecycle rules.

Introduces a generic hard-remove mechanism in the spec/types (removed, replaced_by) and updates cli-core, docs generation, and registry generation to hide removed entries from help/docs while still parsing them to emit a clear redirect-and-exit message.

Removes deprecated commands/flags and their implementations: buckets set-ttl, buckets set-transition, forks commands, plus deprecated --region/--consistency handling in bucket creation/update paths; tests are updated to assert redirect behavior and the new fork flow via buckets create --fork-of / buckets list --forks-of. Dependency @tigrisdata/storage is bumped to ^3.4.0.
