v0.4.0

v0.4.0

Added

• Standalone addon CLI: resmon <addon_name> [-i|-h|-s|-d] inspects,
  samples, or live-demos any fetcher or module on its own, without a
  config file; modes are cumulative, an optional fetch./mod. prefix
  disambiguates a name shared by both kinds.
• Every fetcher/module now carries info/opts metadata (plus ranges
  for fetchers, sample fake-data templates for modules), validated by a
  shared, tightened contract check.
• src/fake_fetcher.lua: seeded noise generator driving -s/-d fake
  data from each module's sample template; history-graph modules get
  their rolling window pre-filled before a static -s render.
• NONE sentinel for a fetcher = {...} slot that should stay
  intentionally empty.
• --list (enumerate every installed fetcher/module), --include <path>
  (additive dev/test directory, takes priority on a name collision),
  -o/--options <{lua-table}> (CLI-side config override), -r/--refresh
  extended to also pace a module's fake-data tick.
• Global path flags (--config-dir/-c/--config-file/--fetchers-dir/
  --modules-dir) now recognized anywhere on the command line.
• config/fetcher_addon_sample.lua, config/module_addon_sample.lua,
  config/ADDON-AUTHORING.md: ready-to-copy addon skeletons and a
  walkthrough, installed by both make install-config and the release
  tarball's install.sh.
• dist/install.sh: detects an existing install and its version;
  automatically migrates a 0.3.0 config/addons to the new naming, or
  backs up and resets config.lua for anything older/unrecognized;
  --upgrade skips the confirmation prompt.

Fixed

• prefill_module_history no longer re-polls a real (-f-attached)
  fetcher during its synthetic history replay — was hanging on
  pipe-based fetchers and corrupting delta-based ones.
• -d on a module now actually respects its refresh rate, gated per
  cache slot instead of ticking unconditionally.
• -d/-s on a fetcher now render nested-table values and
  embedded-JSON string fields legibly instead of skipping/dumping them
  raw.
• -s pane width now correctly reaches half the terminal width instead
  of being capped too low.
• -s history prefill now respects an -o-overridden interval
  instead of always using the addon's static default.

Changed

• Custom module filenames and config mod = "..." values dropped the
  redundant mod_ prefix (mods/clock_graph.lua, mod = "clock_graph");
  fetcher naming is unchanged.
• Standalone-CLI and --help/--list output reformatted: a single
  banner/trailing-blank-line per invocation, terminal-width-aware
  word-wrapped tables, right-aligned -i/--info metadata,
  [VALID]/[FAULT] dependency markers.
• README overhauled throughout (new Standalone addon CLI section + demo
  GIF, Built-in Monitors table, Contributing points at the
  addon-authoring samples).
