feat(fetch): Add company-specific job search capabilities

[wallentx]

This pull request introduces a new capability for targeted company job searches, allowing the system to fetch jobs specifically for a given company, with support for company aliases and website verification. It adds a new API for company-specific job fetching, refines the job filtering logic to ensure accurate company matches, and adapts job source selection and prompt generation accordingly. Several changes also ensure that RSS and API sources are excluded from company-targeted searches, and comprehensive tests are added to validate the new matching logic.

Company-targeted job fetching and filtering:

• Added CompanyFetchOptions and companyFetchScope types, along with logic to activate company-specific fetches, aggregate company names/aliases, and match company websites. Introduced filterJobsByCompanyTarget and jobMatchesCompanyTarget to filter results by company name, aliases, and website, ensuring only relevant jobs are returned. [1] [2]
• Implemented the FetchCompanyJobsSkippingExistingWithCandidateCache function, which disables RSS and API sources for company fetches and invokes the new scoped job fetching logic.
• Modified the main job fetching pipeline to apply company filtering after all jobs are fetched, and to record filtered-out jobs in the summary.

Source selection and prompt adaptation:

• Adjusted source resolution and fetching logic to use company-specific criteria when a company fetch is active, including disabling RSS and API sources, customizing LLM prompts, and generating site search URLs for the target company. [1] [2] [3] [4] [5] [6] [7]
• Added buildCompanyLLMSearchPrompt to generate LLM prompts tailored to company-targeted searches, including company details, aliases, website, and candidate criteria as needed.

Testing and company name normalization:

• Added a unit test (TestJobMatchesCompanyTargetUsesWebsiteAndAliases) to verify company matching by name, alias, and website.
• Updated cleanCompanyName to recognize "llc" and "llc." as company suffixes for improved normalization.

Pull request overview

This PR reworks the TUI fetch command from a general-purpose job search (with flags like --sources, --candidate-limit, --accepted-limit, --no-llm) to a company-targeted search (fetch <company> [--aka <name>] [--website <url>] [--all]). It adds new company matching logic in the fetcher layer, adapts source selection and LLM prompts for company-specific searches, and refactors the command footer view with dynamic height pinning.

Changes:

• Introduces CompanyFetchOptions, companyFetchScope, and FetchCompanyJobsSkippingExistingWithCandidateCache in the fetcher, with company name/alias/website matching, post-fetch filtering, and company-targeted LLM/site-search prompts; disables RSS and API sources for company fetches
• Replaces the old fetch command options and :help command in the TUI with company-targeted parsing, ghost hints, and tab completions; consolidates command result clearing into clearOperatorCommandResult
• Extracts the command footer into commandFooterView() with a reserved completion line and pins it to the terminal bottom via composeTableAndHelpView
