holbuild v0.8.2

holbuild v0.8.2

Added

• Added optional Bazel-style HTTP remote cache support via --remote-cache and HOLBUILD_REMOTE_CACHE_URL.
• Remote cache entries use /ac/<action-key> metadata and /cas/<sha256> content blobs.
• CAS transfers support zstd compression where available.
• Added support for HOLBUILD_REMOTE_CACHE_CURL_CONFIG to pass curl configuration, useful for private cache authentication.
• Added build.exclude_globs for package-relative glob exclusions.

Changed

• build.exclude now represents concrete package-relative paths/subtrees. Glob patterns in build.exclude are still accepted but deprecated and produce a
  warning.
• Source discovery now ignores nested holbuild subprojects by default, unless explicitly listed as members.
• Checkpoint budget enforcement now runs during builds between completed nodes and avoids evicting checkpoint families that may be in active use.

Fixed

• Prevented parent projects from accidentally discovering sources inside nested holbuild subprojects.
• Improved checkpoint budget behavior for long builds and retained proof-edit checkpoints.

Documentation

• Updated README, design notes, manifest/local config references, and holbuild skill documentation for remote cache, excludes, and checkpoint retention.
